LP2980-N - Micropower 50-mA Ultra-Low-Dropout Regulator

General Description

The LP2980-N is a fixed-output, wide-input, lowdropout (LDO) voltage regulator supporting an input voltage range from 2.5 V to 16 V and up to 50 mA of load current.

The LP2980-N supports an output range of 1.2 V to 5.0 V (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:.
  • ±0.5% for A-grade legacy chip.
  • ±1% for standard-grade legacy chip.
  • ±0.5% for new chip (A grade and standard grade).
  • Output accuracy over load, and temperature: ±1% (new chip).
  • Output current: Up to 50 mA.
  • Low IQ (new chip): 69 μA at ILOAD = 0 mA.
  • Low IQ (new chip): 380 μA at ILOAD = 5.
