Overview

The HT78Rxx series positive linear regulators feature low quiescent current and low dropout characteristics, making them suitable for battery-powered applications. Available in space-saving packages, the series delivers a continuous output current of 500mA. Multiple fixed output voltage options are provided, with voltage and current adjustment achievable via external components. The series integrates thermal shutdown and current limiting protection to handle demanding operating conditions.
