Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for

stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational

sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may

remain possibility to affect device reliability.

Note 2. Devices are ESD sensitive. Handling precaution recommended.

Note 3. The device is not guaranteed to function outside its operating conditions.

Note 4. θ_JAis measured in the natural convection at T_A= 25°C on a low effective thermal conductivity test board of JEDEC 51-3

thermal measurement standard. The case position of θ_JCis on the exposed pad for the WDFN-6L 2x2 packages.

Note 5. Quiescent, or ground current, is the difference between input and output currents. It is defined by I_Q= I_IN- I_OUTunder no

load condition (I_OUT= 0mA). The total current drawn from the supply is the sum of the load current plus the ground pin

current.

Note 6. The dropout voltage is defined as V_IN-V_OUT, which is measured when V_OUTis V_OUT(NORMAL)- 100mV.

Note 7. Regulation is measured at constant junction temperature by using a 2ms current pulse. Devices are tested for load

regulation in the load range from 10mA to 500mA.

Applications Information

Enable

The RT9013 goes into sleep mode when the EN pin is in a

logic low condition. During this condition, the RT9013 has

an ENpin to turn on or turn off regulator, When the ENpin

is logic hight, the regulator will be turned on. The supply

current to 0.7μA typical. The EN pin may be directly tied

to V_INto keep the part on. The Enable input is CMOS

logic and cannot be left floating.

Like any low-dropout regulator, the external capacitors used

with the RT9013 must be carefully selected for regulator

stability and performance. Using a capacitor whose value

is > 1μF on the RT9013 input and the amount of capacitance

can be increased without limit. The input capacitor must

be located a distance of not more than 0.5 inch from the

input pin of the IC and returned to a clean analog ground.

Any good quality ceramic can be used for this capacitor.

The capacitor with larger value and lower ESR (equivalent

series resistance) provides better PSRR and line-transient

response.

PSRR

The power supply rejection ratio (PSRR) is defined as the

gain from the input to output divided by the gain from the

supply to the output. The PSRR is found to be

The output capacitor must meet both requirements for

minimum amount of capacitance and ESR in all LDOs

application. The RT9013 is designed specifically to work

with low ESR ceramic output capacitor in space-saving

and performance consideration. Using a ceramic capacitor

whose value is at least 1μF with ESR is > 20mΩ on the

RT9013 output ensures stability. The RT9013 still works

well with output capacitor of other types due to the wide

stable ESR range. Figure 1. shows the curves of allowable

ESR range as a function of load current for various output

capacitor values. Output capacitor of larger capacitance

can reduce noise and improve load transient response,

stability, and PSRR. The output capacitor should be located

not more than 0.5 inch from the VOUT pin of the RT9013

and returned to a clean analog ground.

PSRR = 20×log

⎜

⎝

⎠

Note that when heavy load measuring, Δsupply will cause

Δtemperature. And Δtemperature will cause Δoutput

voltage. So the heavy load PSRR measuring is include

temperature effect.

Current limit

The RT9013 contains an independent current limiter, which

monitors and controls the pass transistor's gate voltage,

limiting the output current to 0.6A (typ.). The output can

be shorted to ground indefinitely without damaging the part.

Thermal Considerations

Thermal protection limits power dissipation in RT9013.

When the operation junction temperature exceeds 170°C,

the OTP circuit starts the thermal shutdown function and

turns the pass element off. The pass element turn on again

after the junction temperature cools by 30°C.

surroundings airflow and temperature difference between

junction to ambient. The maximum power dissipation can

Where T_J(MAX)is the maximum operation junction

temperature, T_Ais the ambient temperature and the θ_JAis

the junction to ambient thermal resistance.

For recommended operating conditions specification of

RT9013, where T_J(MAX)is the maximum junction

temperature of the die (125°C) and T_Ais the operated

ambient temperature. The junction to ambient thermal

resistance θ_JA(θ_JAis layout dependent) for WDFN-6L 2x2

package is 165°C/W, SOT-23-5 package is 250°C/W and

SC-70-5 package is 333°C/W on the standard

JEDEC 51-3 single-layer thermal test board. The maximum

power dissipation at T_A= 25°C can be calculated by

following formula :

P_D(MAX)= (125°C − 25°C) / 165 = 0.606 W for

WDFN-6L 2x2 packages

P_D(MAX)= (125°C − 25°C) / 250 = 0.400 W for SOT-23-5

packages

P_D(MAX)= (125°C − 25°C) / 333 = 0.300 W for SC-70-5

packages

The maximum power dissipation depends on operating

ambient temperature for fixedT_J(MAX)and thermal resistance

θ_JA. For RT9013 packages, the Figure 2 of derating curves

allows the designer to see the effect of rising ambient

temperature on the maximum power allowed.
