LM7705MM/NOPB Description

Short technical summary and product information.

The LM7705MM/NOPB from Texas Instruments is a switched capacitor voltage inverter designed to provide a low-noise, fixed negative bias voltage. This device is crucial for applications using low-voltage amplifiers, enabling their output to swing closer to zero volts by supplying a small negative rail. It generates a stable -0.232V output with a tolerance of 5% from an input supply voltage ranging from 3V to 5.25V.

 

Key electrical characteristics include a maximum output current of 26mA, a low quiescent current of 78µA, and a shutdown current of 20nA. The device operates with an efficiency of up to 98% and features a turn-on time of 500µs. It is designed for operation within an ambient temperature range of -40°C to 125°C.

 

The LM7705MM/NOPB is available in an 8-pin VSSOP package, suitable for surface mounting. This compact package is ideal for space-constrained designs. The device includes an enable feature for power management and operates as a charge pump topology without synchronous rectification.
