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
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
