LM7705MM/NOPB TI Negative Bias Generator | 8-VSSOP | 5V to 15V Input, -0.23V Output

Product Overview

The LM7705MM/NOPB from Texas Instruments is a switched capacitor voltage inverter designed to generate a regulated negative bias voltage from a positive input supply. It operates with an input voltage range of 5V to 15V and provides a fixed -0.23V output with ±3% accuracy. Housed in an 8-pin VSSOP package, this device is ideal for applications requiring a small negative bias rail, such as operational amplifier supplies, LCD bias, and sensor biasing. Its low quiescent current (typically 1.5 mA) and high efficiency make it suitable for battery-powered and space-constrained designs.
