LM27762DSST TI Power Management IC | 12-WSON (3x2) | Inverting Charge Pump, Low Noise

Product Overview

The LM27762DSST from Texas Instruments is a high-performance, low-noise inverting charge pump with integrated LDOs, designed to generate a regulated negative output voltage from a positive input supply. Housed in a compact 12-WSON (3x2) package, it delivers up to 250mA output current with excellent line and load regulation. The device operates over a wide input voltage range of 2.7V to 5.5V, making it ideal for battery-powered and industrial applications requiring a clean negative rail.
