BA18BC0FP-E2

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

The BA18BC0FP-E2 is a fixed-output Low Dropout (LDO) regulator manufactured by ROHM Semiconductor, designed for stable voltage regulation with a maximum output current of 1A. It features a fixed output voltage accuracy of ±2.0% at 25°C and operates within an input voltage range of 3V to 16V, with a maximum withstand voltage of 18V. The device exhibits a typical dropout voltage of 0.3V at 0.2A load and provides ripple rejection of 55dB. Integrated protections include thermal shut-down and over-current protection. It is housed in a TO-252-3 package and supports an operating temperature range from -40°C to 105°C.
