LM2788MM-1.8/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2788MM-1.8/NOPB is a positive fixed voltage regulator IC manufactured by National Semiconductor, now part of Texas Instruments. It utilizes a charge pump topology for step-down voltage regulation. The device provides a fixed output voltage of 1.8V with a maximum output current of 120mA. It operates with an input voltage range starting from a minimum of 2.6V. The component is housed in an 8-VSSOP or 8-MSOP package, measuring 3.00mm in width. It features low noise and low dropout voltage characteristics.
