ST730M33R Description

Short technical summary and product information.

The STMicroelectronics ST730M33R is a linear voltage regulator featuring a fixed positive output and an enable control feature. It is designed to operate with an input voltage of up to 28V and provides a regulated output with a dropout voltage of 1.2V at 300mA. The device includes protection features such as over current and over temperature.

 

This regulator is suitable for applications requiring stable voltage regulation. Its PSRR is rated between 75dB and 35dB across a frequency range of 120Hz to 100kHz, indicating good noise rejection capabilities. The operating temperature range is from -40°C to 125°C (TA).

 

The ST730M33R is supplied in a SOT-23-5 package, also referred to as SC-74A or SOT-753, and is designed for surface mount applications. It has a low quiescent current of 10 µA, making it suitable for power-sensitive designs.
