BA09SFP-E2

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

The BA09SFP-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 9 V output with a maximum continuous current of 1 A. The device operates within an input voltage range of 9 V to 25 V and withstands up to 35 V. Key electrical specifications include a typical ripple rejection ratio of 55 dB, a maximum dropout voltage of 500 mV at 500 mA, line regulation of 100 mV, and load regulation of 50 mV. It functions reliably across an operating temperature range from -40 °C to +85 °C.
