LM2788MM-1.8

Voltage Regulators - DC DC Switching Regulators Overview

The LM2788MM-1.8 is a fixed-output charge pump voltage regulator manufactured by National Semiconductor, now under Texas Instruments. It provides a regulated 1.8V output with a maximum continuous current of 120mA. The device operates from an input voltage range of 2.6V to 5.5V and utilizes a 500kHz switching frequency. It is housed in an 8-VSSOP surface-mount package and supports an operating temperature range of -40°C to 85°C.
