US1205

300 mA LOW DROPOUT POSITIVE

ADJUSTABLE REGULATOR

PRELIMINARY DATASHEET

FEATURES

DESCRIPTION

SOT23 package

The US1205 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

shutdown.

Stable with 2.2uF ceramic capacitor

1% Voltage Reference Accuracy

Only 270mV Dropout at 300 mA

170mV Dropout at 150mA

10nA Quiescent Current in Shutdown

Current Limit and Thermal Shutdown

Logic input Enable pin

The US1205 is available in fixed and adjustable output

voltage versions in a small SOT23-5 package.

APPLICATIONS
