BA78M08FP-E2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BA78M08FP-E2 is a fixed positive linear voltage regulator from the ROHM BA78M series, housed in a TO-252-3 surface-mount package. It provides a fixed 8V output with a maximum current of 500mA. The device operates within an input voltage range of 10.5V to 23V and supports a maximum power dissipation of 10W. Electrical specifications include a line regulation of 10mV, load regulation of 20mV, and a typical power supply rejection ratio (PSRR) of 78dB. It functions reliably across an operating temperature range of -40°C to +85°C.
