Designed to meet the requirements of RF and analog circuits, the LP5912Q1 device provides low noise, high PSRR, low quiescent current, and low line and load transient response.
The LP5912-Q1 offers class-leading noise performance without a noise bypass capacitor and with the ability for remote output capacitance placement.
The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (no separate noise bypass capacitor required).
This device is available with fixed output voltages from 0.
8 V to 5.
5 V in 25-mV steps.
