Product Information
Product Overview
ST732M33R is a 300mA LDO regulator, designed to be used in several medium voltage applications. Ultra-low quiescent current of 5µA makes it suitable for applications permanently connected to power supply/battery. This feature is also useful when electronic modules remain permanently turned on. This device 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. It is used in applications such as post regulation, electronic meters, smoke detectors / alarms, portable equipment, industrial applications.
- Wide input voltage range from 2.5V to 28V
- Output voltage accuracy is +1% maximum at (TA = +25°C, VIN = VOUT + 1V)
- Stable with low ESR capacitors (0.47µF min.), 3.3V output voltage
- Thermal shutdown protection, current limit protection
- Quiescent current is 5µA typical at (IOUT = 0mA, TA = +25°C)
- Output noise voltage is 70µVRMS/VOUT typical at (f = 10Hz to 100KHz, IOUT = 10mA COUT = 1µF)
- Supply voltage rejection is 75dB typical at (VIN = VOUT(NOM) + 1V +/- VRIPPLE)
- Dropout voltage is 200mV typical at (IOUT = 100mA, VIN = VOUT(NOM) - 0.1V)
- Operating temperature range from -40°C to +125°C
- 5-lead SOT23 package
