BA78M09FP-E2 Description

Short technical summary and product information.

The BA78M09FP-E2 is a single-output positive fixed linear voltage regulator from ROHM Semiconductor. It provides a regulated 9V output with a maximum output current of 500mA. The device features a typical dropout voltage of 2V at 500mA load.

 

This regulator includes over-current and over-temperature protection for reliable operation. It offers a power supply rejection ratio (PSRR) of 67dB at 120Hz, making it suitable for noise-sensitive applications. The operating temperature range spans from -40°C to +85°C.

 

The BA78M09FP-E2 is offered in a surface-mount TO-252-3 (DPak) package, which is designed for efficient heat dissipation. The mounting type is surface mount, compatible with standard SMD assembly processes.
