ST730MR LDO Regulator

STMicroelectronics' ST730MR features a 300 mA, 28V low-dropout voltage regulator with 5 µA quiescent current

Image of ST Microelectronics' ST730MR LDO regulator ST Microelectronics' ST730 is a 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 and battery. This feature is also useful when electronic modules remain permanently turned on. The ST730 embeds protection functions, such as current limit, short-circuit, and thermal shutdown. The extended input voltage range, very low drop voltage, and low quiescent current features make it suitable also for low-power after-market automotive and consumer applications.

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 current up to 300 mA
  • High output voltage accuracy: ±0.5% @ 25 °C, ±1% across temperature range
Applications
  • Post regulation
  • Electronic meters
  • Smoke detectors/alarms
  • Portable equipment
  • Industrial applications
