US1150 Datasheet | UNISEM

4A ULTRA LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR PRELIMINARY DATASHEET Features 0.7V Dropout at 4A Fast Transient Response 1% Voltage Reference Initial Accuracy Built-in Thermal Shutdown DESCRIPTION The US1150 product is a 4A regulator with extremely low dropout voltage using a proprietary Bipolar process that achieves parable equivalent on resistance to that of discrete MOSFETs. This product is specifically designed to provide well regulated supply for applications requiring 2.8V or lower voltages from 3.3V ATX power supplies where high efficiency of a switcher can be achieved without the cost and plexity associated with switching regulators. One such application is the...
