Notes:  
1. Exceeding the absolute maximum rating may damage the device.  
2. The device is not guaranteed to function outside its operating rating.  
3. PD(max) = (TJ(max) – TA) / θJA, where θJA, depends upon the printed circuit layout. See “Applicatins Information.”  
4. Devices are ESD sensitive. Handling precautions recommended.  
5. Specification for packaged product only.  
6. VDO = VIN – VOUT when VOUT decreases to 98% of its nominal output voltage with VIN = VOUT + 1V. For output voltages below 1.75, dropout voltage  
specification does not apply due to a minimum input operating voltage of 2.25V.  
7. IGND is the quiescent current. IIN = IGND + IOUT  
.
8. For a 2.5V device, VIN = 2.250V (device is in dropout).

Enable/Shutdown  
The MIC37300/01/02/03 is a high-performance low-  
dropout voltage regulator suitable for moderate to  
high-current regulator applications. Its 500mV dropout  
voltage at full load and over-temperature makes it  
especially valuable in battery-powered systems and  
as high-efciency noise lters in post-regulator  
applications. Unlike older NPN-pass transistor  
designs, there the minimum dropout voltage is limited  
by the based-to-emitter voltage drop and collector-to-  
emitter saturation voltage, dropout performance of the  
PNP output of these devices is limited only by the low  
VCE saturation voltage.  
associated

sink  
without  
compromising  
performance. When this technique is employed, a  
capacitor of at least 1.0µF is needed directly between  
the input and regulator ground.  
Refer to “Application Note 9” for further details and  
examples on thermal design and heat sink  
applications.  
A trade-off for the low dropout voltage is a varying  
base drive requirement. Micrel’s Super ßeta PNP®  
process reduces this drive requirement to only 2% to  
5% of the load current.  
Output Capacitor  
The MIC37300/01/02/03 requires an output capacitor  
for stable operation. As  
a
µCap LDO, the  
The MIC37300/01/02/03 regulator is fully protected  
from damage due to fault conditions. Current limiting  
is provided. This limiting is linear; output current  
during overload conditions is constant. Thermal  
shutdown disables the device when the die  
temperature exceeds the maximum safe operating  
temperature. The output structure of these regulators  
allows voltages in excess of the desired output  
voltage to be applied without reverse current ow.  
MIC37300/01/02/03 can operate with ceramic output  
capacitors as long as the amount of capacitance is  
47µF or greater. For values of output capacitance  
lower than 47µF, the recommended ESR range is  
200mto 2. The minimum value of output  
capacitance recommended for the MIC37300 is 10µF.  
For 47µF or greater, the ESR range recommended is  
less than 1. Ultra-low ESR, ceramic capacitors are  
recommended for output capacitance of 47µF or  
greater to help improve transient response and noise  
reduction at high frequency. X7R/X5R dielectric-type  
ceramic capacitors are recommended because of  
their temperature performance. X7R-type capacitors  
change capacitance by 15% over their operating  
temperature range and are the most stable type of  
ceramic capacitors. Z5U and Y5V dielectric capacitors  
change value by as much as 50% and 60%,  
respectively, over their operating temperature ranges.  
To use a ceramic chip capacitor with Y5V dielectric,  
the value must be much higher than an X7R ceramic  
capacitor to ensure the same minimum capacitance  
over the equivalent operating temperature range.  
Thermal Design  
Linear regulators are simple to use. The most  
complicated design parameters to consider are  
thermal characteristics. Thermal design requires the  
following application-specic parameters:  
Maximum ambient temperature (TA)  
Output current (IOUT  
)
Output voltage (VOUT  
Input voltage (VIN)  
)
Ground current (IGND  
)
First, calculate the power dissipation of the regulator  
from these numbers and the device parameters from  
this datasheet.  
Input Capacitor  
An input capacitor of 1.0µF or greater is  
recommended when the device is more than 4 inches  
away from the bulk supply capacitance, or when the  
supply is a battery. Small, surface-mount chip  
capacitors can be used for the bypassing. The  
capacitor should be place within 1" of the device for  
optimal performance. Larger values will help to  
improve ripple rejection by bypassing the input to the  
regulator, further improving the integrity of the output  
voltage.  
PD = (VIN – VOUT) IOUT + VIN IGND  
where the ground current is approximated by using  
numbers from the “Electrical Characteristics” or  
“Typical Characteristics.” Then the heat sink thermal  
resistance is determined with this formula:

SA = ((TJ(max) – TA)/ PD) – (θJC + θCS)

Enable Input  
The MIC37301/02/03 also features an enable input for  
on/off control of the device. Its shutdown state draws  
“zero” current (only microamperes of leakage). The  
enable input is TTL/CMOS compatible for simple logic  
interface, but can be connected up to VIN. When  
enabled, it draws approximately 15µA.  
The MIC37300/01/02/03 has excellent transient  
response to variations in input voltage and load  
current. The device has been designed to respond  
quickly to load current variations and input voltage  
variations. Large output capacitors are not required to  
obtain this performance. A standard 47µF output  
capacitor, preferably tantalum, is all that is required.  
Larger values help to improve performance even  
further.

By virtue of its low-dropout voltage, this device does  
not saturate into dropout as readily as similar NPN-  
based designs. When converting from 3.3V to 2.5V,  
2.5V to 1.8V or 1.65V, or 2.5V to 1.5V, the NPN-  
based regulators are already operating in dropout,  
with typical dropout requirements of 1.2V or greater.  
To convert down to 2.5V without operating in dropout,  
NPN-based regulators require an input voltage of 3.7V  
at the very least. The MIC37300/01/02/03 regulator  
will provide excellent performance with an input as low  
as 3.0V or 2.25V, respectively. This gives the PNP-  
based regulators a distinct advantage over older,  
NPN-based linear regulators.

Figure 1. Adjustable Regulator with Resistors  
The MIC37302 and MIC37303 allow programming the  
output voltage any-where between 1.24V and the  
5.5V maximum operating rating of the family. Two  
resistors are used. Resistors can be quite large, up to  
1M, because of the very high input impedance and  
low bias current of the sense comparator. The resistor  
values are calculated by:  
Minimum Load Current  
The MIC37300/01/02/03 regulator is specied  
between nite loads. If the output current is too small,  
leakage currents dominate and the output voltage  
rises. A 10mA minimum load current is necessary for  
proper operation.

Where VOUT is the desired output voltage. Figure 1  
shows component denition. Applications with widely  
varying load currents may scale the resistors to draw  
the minimum load current required for proper  
operation (see above).  
Error Flag  
The MIC37301 and MIC37303 feature an error ag  
circuit that monitors the output voltage and signals an  
error condition when the voltage is 5% below the  
nominal output voltage. The error ag is an open-  
collector output that can sink 10mA during a fault  
condition.  
Low output voltage can be caused by a number of  
problems, including an overcurrent fault (device in  
current limit) or low input voltage. The ag is  
inoperative during overtemperature shutdown.
