Functional Description

The YB1200 is an ultra-low-noise,

low-quiescent current, low-dropout linear

regulator. It is supplied in a SC-70 and

SC-82 package for space and noise

sensitive applications. These devices can

supply loads up to 150mA. As shown in the

Functional Block Diagram, the YB1200

consists of a reference and noise bypass

circuit, error amplifier, output drive

transistor, internal feedback voltage divider,

thermal sensor, and short circuit current

limiter. The internal reference is connected

to the error amplifier’s inverting input. The

error amplifier compares this reference with

the feedback voltage and amplifies the

difference. If the feedback voltage is lower

transistor gate is pulled high, allowing less

current to pass to the output. The parts are

available with preset output voltages

ranging from 1.8V to 3.3V.

Stability

The YB1200 is a high performance LDO

emphasizing stability with low output

capacitance. It is able to maintain stability

with an output capacitor as low as 0.47uF.

The output capacitor can also be increased

to optimize performance. The YB1200 will

remain stable and in regulation with no load,

unlike many other voltage regulators.

The YB1200 features a low impedance

P-channel MOSFET pass transistor. This

provides several advantages over similar

designs using a PNP pass transistor,

including low operating power and longer

pass-transistor gate is pulled low. This

allows more current to pass to the output

and increases the output voltage. If the

feedback voltage is too high, the pass

90µA of quiescent current under most

conditions.

Output Short-Circuit Current Limit

Application Information

The YB1200 includes a current limiter,

which monitors and controls the pass

transistor’s gate voltage, limiting the output

current to about 200 mA, for example, in a

short-circuit output situation.

Enable/Shutdown

The YB1200 comes with an active-high

enable pin that allows the regulator to be

enabled. Forcing the enable pin low

disables the regulator and puts it into the

shutdown mode. This pin cannot be left

floating as it may cause an undetermined

state.

Shutdown

The YB1200 also features a low-power

active shutdown mode. It has a switch that

turns off the device when disabled. This

allows the output capacitor and load to

discharge and de-energize the load. In the

shutdown mode, the internal functional

blocks, such as voltage reference and the

error amplifier, are turned off completely,

and the quiescent current is less than 1µA.

Input/Output Capacitor

It is recommended to use a 0.47µF

capacitor on the YB1200 input and a

0.47µF capacitor on the output. For high

regulation performance, larger input

capacitor values and lower ESRs provide

better noise rejection and line-transient

response. The output noise, load-transient

response, stability, and power-supply

rejection can be improved by using large

output capacitors. Low ESR ceramic

capacitors provide optimal performance

and save space.

Thermal Protection Shutdown

The thermal protection shutdown function

protects the device from operating in over

temperature condition. When the junction

temperature exceeds +160°C, the thermal

sensor signals the shutdown logic, turning

off the pass transistor and allowing the IC

to cool down. The thermal sensor turns the

pass transistor on again after the IC’s

junction temperature drops to +140°C.

Power Supply Rejection and Transient

Response

The PSRR and transient response can be

improved by increasing the values of the

input and output bypass capacitors, and

through passive filtering techniques.

Soft-Start Circuitry

The YB1200 includes a soft-start circuitry to

limit inrush current at turn-on. During power

up, the output capacitor and output load are

charged with a reduced output current.
