1A VERY LOW DROPOUT POSITIVE

FIXED AND ADJUSTABLE REGULATORS

DESCRIPTION

FEATURES

Low Dropout Voltage (500mV at 1A)

The APU1206 family of devices are ultra low dropout 1A

regulators using PNP transistor as the pass element.

These products are ideal when a single input supply is

1% Voltage Reference Accuracy

Low Ground Current

1µA Maximum Quiescent Current in Shutdown

(APU1207, APU1208)

only available and the dropout voltage is less than 1V,

exceeding the minimum dropout characteristics of NPN/

PNP hybrid regulators. One common application of these

regulators is where input is 3.3V and a 2.5V output is

needed.

Fast Transient Response

Current Limit and Thermal Shutdown

Error Flag Signal for Output out of Regulation

(APU1207, APU1208)

RoHS Compliant

Besides the low dropout of less than 0.5V, other fea-

tures of the family of the parts are: micro-power shut-

down capability and output UVLO detection where Flag

pin is switched low when output is below 5% of its nomi-

nal point.

APPLICATIONS

2.5V Supply from 3.3V Input for the new

generation of Logic ICs

Computer Mother Board, Add-On Cards

High Efficiency Post Regulator in Switch Mode
