LD56100 - 1A very low dropout fast transient ultra-low noise linear regulator

Datasheet Summary

Description

The LD56100 high accuracy voltage regulator provides 1 A of current from an input voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 120 mV.

It is available in DFN8 (1.2 x 1.6 mm) package, allowing the maximum space saving.

Features

  • Input voltage from 1.8 to 5.5 V.
  • Ultra-low dropout voltage (120 mV typ. at 1 A load and VOUT = 3.3 V).
  • Very low quiescent current (100 µA typ. at no-load, 0.03 µA typ. in off mode).
  • Output voltage tolerance: ± 1% from -40 °C to +85 °C.
  • Ultra-low Noise: 13 µV RMS Noise from 10 Hz to 100 kHz at VOUT = 3.0 V.
  • High PSRR (70 dB@1 kHz).
  • Wide range of output voltages available on request: from 1.0 V up to 5.0 V in 50 mV step.
  • Logi.
