## Description
The LP5910 is a low-noise LDO supplying up to 300 mA. Designed for RF and analog circuits, it offers low noise, high PSRR, low quiescent current, and superior transient response. It features class-leading noise performance without a bypass capacitor and supports remote capacitor placement. A reverse current protection circuit prevents reverse current flow, and an automatic output discharge circuit enables fast turnoff. It's well-suited as a post DC-DC regulator or for single/dual-cell applications, operating with 1-µF input and output ceramic capacitors. Fixed output voltages are available from 0.8 V to 2.3 V in 25-mV steps.

## Specifications
️· Absolute Maximum Ratings: VIN/VOUT: -0.3 to 3.6 V, IQ: 25 µA (no load), TJ(MAX): 150°C
