LM27761DSGT TI Power Management IC | 8-WSON (2x2) | -5V Output, 250mA

Product Overview

The LM27761DSGT is a high-performance, low-noise, regulated switched capacitor voltage inverter from Texas Instruments. It generates a regulated negative output voltage from a positive input voltage, making it ideal for applications requiring a negative rail. The device operates with an input voltage range of 2.7V to 5.5V and delivers up to 250mA of output current. The output voltage is adjustable via external resistors or fixed at -5V. The LM27761DSGT is housed in a compact 8-WSON (2x2 mm) package, enabling space-constrained designs.
