LM2738 - Step-Down DC-DC Switching Regulator

Description

The LM2738 regulator is a monolithic, highfrequency, PWM step-down DC-DC converter in an 8pin WSON or 8-pin MSOP-PowerPAD package.

It provides all the active functions for local DC-DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.

Features

  • 1 Space-Saving WSON and MSOP-PowerPAD™ Packages.
  • 3-V to 20-V Input Voltage Range.
