LP5922 - Texas Instruments

LP5922 Adjustable LDO

The LP5922 is 2-A low dropout (LDO) linear regulator with 200-mV typical dropout voltage at maximum current levels. The LP5922 device can operate from a voltage rail down to 1.3 V without additional bias supply. System efficiency is maximized and power dissipation minimized by the low dropout and low VIN capability. The device also features low quiescent cur.
