UNISONIC TECHNOLOGIES CO., LTD M29150A/B
1.5A, VERY LOW DROP VOLTAGE REGULATORS
DESCRIPTION
As the UTC linear integrated LDO, the UTC M29150A/B shows a high current, high accuracy, low-dropout voltage. The features are: 400mV dropout voltage, very low ground current. Cause the series have been designed for high current loads, so they are also used in lower current, extremely low dropout-critical systems (in which their tiny dropout voltage and ground current values are important attributes).
LINEAR INTEGRATED CIRCUIT
FEATURES
* Very low dropout voltage : typ. 0.4@IOUT=1.5A * Output current guaranteed 1.5A * Fixed and adjustable output voltage * Thermal limit and Internal current * Logic controlled electronic shutdown available * Over voltage protection
