LDFMPVR ST Power Management IC | 6-DFN(2x2) | 5.5V Input, 300mA Output

Product Overview

The LDFMPVR from STMicroelectronics is a high-performance, low-dropout linear voltage regulator designed for space-constrained applications. Housed in a compact 6-DFN (2x2 mm) package, it delivers up to 300 mA output current with a dropout voltage as low as 200 mV at full load. The device operates over a wide input voltage range from 2.5 V to 5.5 V, making it suitable for battery-powered and portable electronics. Its low quiescent current (typically 30 µA) and high PSRR (70 dB at 1 kHz) ensure clean and stable power delivery.
