Product Introduction

Overview

The MC78LC33NTR is a part of the MC78LC00 series of fixed output low dropout linear regulators produced by onsemi. These regulators are designed for handheld communication equipment and portable battery-powered applications that require low quiescent current. Each device in the series includes a voltage reference unit, an error amplifier, a PMOS power transistor, and resistors for setting the output voltage. The MC78LC33NTR is specifically configured to provide a fixed output voltage of 3.3 V.
