BA17810FP-E2

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

The BA17810FP-E2 is a fixed positive linear voltage regulator manufactured by ROHM Semiconductor. It provides a nominal output voltage of 10 V with a maximum continuous output current of 1 A. The device operates within an input voltage range of 12.5 V to 25 V and supports a power dissipation of up to 10 W. It features a line regulation of 15 mV and load regulation of 37 mV, with a typical power supply rejection ratio (PSRR) of 78 dB. The component is housed in a surface-mount TO-252-3 package and functions reliably across an operating temperature range from -40 °C to +85 °C.
