LDFM33PUR Description

Short technical summary and product information.

The STMicroelectronics LDFM33PUR is a linear voltage regulator designed for efficient power management in various electronic applications. It delivers a stable 3.3V output voltage with a maximum output current capability of 500mA. The device operates across a wide temperature range from -40°C to 125°C (TJ).

 

Key electrical characteristics include a low voltage dropout of 0.3V at 500mA and a PSRR ranging from 60dB to 52dB across a frequency band of 120Hz to 100kHz. Protection features such as over current, over temperature, and under voltage lockout (UVLO) are integrated for enhanced reliability. Control features include Enable and Power Good signals.

 

This regulator is housed in a 6-DFN (3x3) package, specifically a 6-VDFN Exposed Pad, designed for surface mount assembly. Its compact size and surface mount capability make it suitable for space-constrained designs.
