DESCRIPTION

FEATURES

SOT-23 Package

The IRU1205 device is an efficient linear voltage regula-

tor with better than 1% initial voltage accuracy, very low

dropout voltage and very low ground current designed

especially for hand held, battery powered applications.

Other features of the device are: TTL compatible enable/

shutdown control input, current limiting and thermal shut-

down.

Stable with 2.2µF Ceramic Capacitor

1% Voltage Reference Accuracy

Only 270mV Dropout at 300mA

and 170mV Dropout at 150mA

5µA Quiescent Current in Shutdown

Current Limit and Thermal Shutdown

Logic Input Enable Pin

The IRU1205 is available in fixed and adjustable output

voltage versions in a small SOT-23 5-Pin package.

APPLICATIONS

Laptop, Notebook & Palmtop computers

Battery Powered Equipments

PCMCIA Vcc & Vpp Regulator

Consumer Electronics

High Efficiency Linear Power Supplies
