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.
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, ± 1% 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
