LD59030 - 300mA very low dropout linear regulator

General Description

The LD59030 high accuracy voltage regulator provides 300 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 135 mV at VOUT = 3.3 V.

It is available in DFN4 1x1 package, allowing the maximum space saving.

Key Features

  • Input voltage from 1.5 to 5.5 V.
  • Ultra low dropout voltage (135 mV typ. at 300 mA load).
  • Very low quiescent current (28 µA typ. at no load, 0.03 µA typ. in off mode).
  • Internal current fold-back.
  • Output voltage tolerance: ± 1 % @ 25 °C.
  • 300 mA guaranteed output current.
  • High PSRR: 75 dB@1 kHz.
  • Wide range of output voltages available on request: from 0.8 V up to 5.0 V in 50 mV step.
  • Logic-controlled electronic shutdo.
