BA25BC0WT

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

The BA25BC0WT is a fixed-output low-dropout (LDO) regulator manufactured by ROHM Semiconductor, designed for applications requiring stable voltage regulation with high current capability. It features a maximum output current of 1A and a fixed output voltage accuracy of ±2.0% at 25°C. The device operates within an input voltage range of 3.5V to 16V, with a maximum withstand voltage of 18V. Key electrical parameters include a typical dropout voltage of 0.3V at 0.2A load, a ripple rejection of 55dB, and a load regulation of 35mV across the full load range. It requires a 22µF output capacitor and functions within an operating temperature range of -40°C to 105°C.
