LD49100 - low-noise regulator

Description

The LD49100 provides 1 A maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 200 mV.

The device is stable with ceramic capacitors on the input and output.

Features

  • AEC-Q100 qualified.
  • Temperature range: -40 °C to 125 °C.
  • Input voltage from 1.5 to 5.5 V.
  • Ultra low-dropout voltage (200 mV typ. at 1 A load).
  • Very low quiescent current (20 µA typ. at no load, 200 µA typ. at 1 A load, 1 µA max. in off mode).
  • Very low-noise with no bypass capacitor (30 µVRMS at VOUT = 0.8 V).
  • Output voltage tolerance: ± 2.0% at 25 °C.
  • 1 A guaranteed output current.
  • Wide range of output voltages ava.
