LDBL20 - 200mA very low quiescent current linear regulator

General Description

The LDBL20 high accuracy voltage regulator provides 200 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 200 mV.

It is available in the new STSTAMP™ package, allowing the maximum space saving.

Key Features

  • Input voltage from 1.5 to 5.5 V.
  • Ultra low dropout voltage (200 mV typ. at 200 mA load).
  • Very low quiescent current (20 µA typ. at no-load, 0.03 µA typ. in off mode).
  • Output voltage tolerance: ± 1.5% @ 25 °C.
  • 200 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.
  • Interna.
