BA09CC0FP-E2

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

The BA09CC0FP-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 4 V to 25 V and features a typical dropout voltage of 300 mV at 0.5 A load. It includes integrated thermal shutdown, over-current protection, and over-voltage protection circuits. The regulator maintains a ripple rejection ratio of 55 dB and ensures output accuracy of ±2.0% at 25°C. It is housed in a TO-252-3 surface-mount package and supports an operating temperature range from -40°C to +125°C.
