LM27761DSGR TI Inverting Charge Pump | 8-WSON (2x2) | 250mA, 2.7V-5.5V

Product Overview

The LM27761DSGR is a high-performance inverting charge pump from Texas Instruments, designed to generate a regulated negative output voltage from a positive input supply. Housed in a compact 8-WSON (2x2) package, this device delivers up to 250mA output current with excellent efficiency and low ripple. It operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered and industrial applications. The LM27761DSGR integrates a low-dropout regulator (LDO) post-regulator to provide a clean, low-noise negative rail, essential for precision analog circuits.
