General Description

The LP5910 is a low-noise LDO that can supply up to 300 mA of output current.

Designed to meet the requirements of RF and analog circuits, this device provides low noise, high PSRR, low quiescent current, and superior line transient and load transient response.

Using new innovative design techniques the LP5910 offers class-leading noise performance without a noise bypass capacitor and with the option for remote output capacitor placement.

Key Features

  • 1 Input Voltage Range: 1.3 V to 3.3 V.
  • Output Voltage Range: 0.8 V to 2.3 V.
  • Output Current: 300 mA.
  • PSRR: 75 dB at 1 kHz.
  • Output Voltage Tolerance: ±2%.
