BA78M10FP-E2

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

The BA78M10FP-E2 is a fixed positive linear voltage regulator from the ROHM BA78M series, housed in a surface-mount TO-252-3 package. It provides a fixed output voltage of 10 V with a maximum continuous output current of 500 mA. The device operates within an input voltage range of 12.5 V to 25 V and supports a junction temperature range from -40°C to +85°C. Key electrical specifications include a line regulation of 10 mV, load regulation of 20 mV, and a typical power supply rejection ratio (PSRR) of 78 dB at standard test conditions.
