LDFM33PVR Description

Short technical summary and product information.

The STMicroelectronics LDFM33PVR is a linear voltage regulator designed for efficient power management. It delivers a stable 3.3V output voltage with a maximum current capability of 500mA. The device operates over a wide temperature range from -40°C to 125°C, making it suitable for various environmental conditions.

 

Key electrical features include a low dropout voltage of 0.3V at 500mA and a high Power Supply Rejection Ratio (PSRR) of 60dB to 52dB across a frequency range of 120Hz to 100kHz. Protection features such as over current, over temperature, and under voltage lockout (UVLO) are integrated to ensure reliable operation. The regulator also includes Enable and Power Good control signals.

 

Packaged in a compact 6-DFN (2x2) footprint with surface mount capability, the LDFM33PVR is ideal for space-constrained applications. Its design considerations include robust protection mechanisms and stable voltage regulation for sensitive electronic circuits.
