RT9078-33GJ5 Description

Short technical summary and product information.

The Richtek RT9078-33GJ5 is a linear voltage regulator IC designed for power management applications. It offers a stable, fixed 3.3V output voltage with a maximum output current of 300mA. The device features a low dropout voltage of 0.22V at 300mA, making it efficient for battery-powered devices.

 

Key electrical characteristics include a maximum input voltage of 5.5V and a quiescent current of only 4µA, contributing to low power consumption. Protection features such as over current and over temperature shutdown are integrated to ensure device reliability. The regulator also provides a Power Supply Rejection Ratio (PSRR) of 75dB at 1kHz.

 

This component is housed in a compact TSOT-23-5 package, suitable for surface mounting on printed circuit boards. The operating temperature range is from -40°C to 85°C, allowing for use in various environmental conditions. Its fixed output and enable control feature make it a straightforward choice for designs requiring a reliable voltage regulation.
