ST732 - low-dropout voltage regulator

Description

The ST732 is 300 mA LDO regulator, designed to be used in several medium voltage applications.

Ultra-low quiescent current of 5 µA makes it suitable for applications permanently connected to power supply/battery.

This feature is also useful when electronic modules remain permanently turned on.

Features

  • Wide input voltage range : 2.5 V to 28 V.
  • Ultra-low quiescent current: typ. 5 µA at no-load, 10 µA max. across full temperature range.
  • Output voltage accuracy: ± 2%.
  • Output current up to 300 mA.
  • Fixed output voltage versions, starting from 1.2 V with 100 mV step.
  • Stable with low ESR capacitors (0.47 µF min. ).
  • Thermal shutdown protection.
  • Current limit protection.
  • -40 °C to +125 °C operating temperature range Applic.
