LDFMPUR ST Power Management IC | 6-DFN(3x3) | 1.2A Output, Low Dropout

Product Overview

The LDFMPUR from STMicroelectronics is a high-performance, low-dropout linear voltage regulator designed for space-constrained applications. Housed in a compact 6-DFN (3x3 mm) package, it delivers up to 1.2 A output current with excellent line and load regulation. The device features a wide input voltage range from 2.5 V to 16 V and an adjustable output voltage from 0.8 V to 12 V. Its low dropout voltage (typically 300 mV at 1 A) ensures efficient operation even with small input-output differentials. The LDFMPUR integrates protection features including thermal shutdown, current limit, and reverse current protection, making it ideal for automotive, industrial, and consumer electronics.
