LDO40LPURY Description

Short technical summary and product information.

The STMicroelectronics LDO40LPURY is a linear voltage regulator belonging to the low-dropout (LDO) category. It is designed to provide a stable and adjustable output voltage with a maximum output current of 400 mA. This device features a low quiescent current of 45 µA, making it suitable for power-sensitive applications.

 

The regulator operates with an input voltage up to 38 V and offers an adjustable output voltage. Key protection features include current limit and thermal shutdown, enhancing its reliability in operation. The device is available in a compact 6-DFN (3x3) package, suitable for surface mount applications.

 

With a dropout voltage of 0.27V at 400mA and a PSRR of 77dB ~ 42dB (100Hz ~ 10kHz), the LDO40LPURY provides good performance for various power regulation needs. Its adjustable output and enable control feature offer design flexibility.
