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.

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.

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 capacitors (0.47 µF min.)
  • Thermal shutdown protection
  • Current limit and SOA protection
  • -40 °C to +125 °C operating temperature range
