LP2985 - 150-mA Low-noise Low-dropout Regulator

General Description

The LP2985 is a fixed-output, wide-input, low-noise, low-dropout voltage regulator supporting an input voltage range from 2.5 V to 16 V and up to 150 mA of load current.

The LP2985 supports an output range of 1.2 V to 5.0 V (for new chip).

Key Features

  • VIN range (new chip): 2.5 V to 16 V.
  • VOUT range (new chip):.
  • 1.2 V to 5.0 V (fixed, 100-mV steps).
  • VOUT accuracy:.
  • ±1% for A-grade legacy chip.
  • ±1.5% for standard-grade legacy chip.
  • ±0.5% for new chip only.
  • ±1% output accuracy over load, and temperature for new chip.
  • Output current: Up to 150 mA.
  • Low IQ (new chip): 71 μA at ILOAD = 0 mA.
  • Low IQ (new chip): 750 μA at ILOAD = 150 mA.
  • Shutdo.
