LD39030 - 300mA very low quiescent current linear regulator IC

Description

The LD39030 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 300 mV.

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

Features

  • Input voltage from 1.5 to 5.5 V.
  • Ultra low dropout voltage (300 mV typ. at 300 mA load).
  • Very low quiescent current (20 µA typ at no load, 0.03 µA typ in off mode).
  • Output voltage tolerance: ±0.5 % (A version) or ± 2.0 % @ 25 °C (standard version).
  • 300 mA guaranteed output current.
  • High PSRR (80 dB@1 kHz, 50 db@100 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 shutdown.
  • Int.
