ST730 - 300mA 28V low-dropout voltage regulator

General Description

The ST730 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.

Key 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, 1 μA max. in shutdown.
  • High output voltage accuracy: ± 0.5% @ 25 °C, ± 2.5% across temperature range.
  • Output current up to 300 mA.
  • Fixed output voltage versions, starting from 1.2 V to 12 V with 100 mV step.
  • Adjustable voltage version, starting from 1.2 V to VIN - VDROP.
  • Stable with low ESR capacitor.
