Description

General part information

LP5922 Series

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 VINcapability. The device also features low quiescent current and very low shutdown current.

The LP5922 device was designed to have high PSRR and low output noise to support sensitive analog applications without additional filtering. The output noise can be reduced even further by implementing a small capacitor on the SS/NR pin.

The output voltage is adjustable from 0.5 V to 5 V by an external resistor divider. Enable pin, adjustable soft start and optional Power Good features help with system power sequencing. Inrush current is controlled with the soft start and the device has short circuit and thermal protections.
