LM7705MME/NOPB TI Negative Bias Generator | 8-VSSOP | -0.23V Output, 5.5V Input

Product Overview

The LM7705MME/NOPB is a low-noise, switched capacitor voltage inverter from Texas Instruments, designed to generate a regulated negative bias voltage from a positive supply. It operates from a single 3V to 5.5V input and provides a fixed -0.23V output with excellent line and load regulation. Housed in an 8-pin VSSOP package, this device is ideal for applications requiring a small footprint and low power consumption, such as portable electronics, sensor biasing, and LCD contrast adjustment.
