BA90BC0WT

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

The BA90BC0WT is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor, designed for applications requiring stable voltage regulation with an output current capacity of 1A. The device provides a fixed output voltage of 9V with an accuracy of ±2.0% at 25°C. It operates within a maximum input voltage range of 16V and supports a withstand voltage of up to 18V. Key electrical parameters include a typical dropout voltage of 0.3V at 0.2A output current, a ripple rejection ratio of 55dB, and a load regulation of 35mV across the full load range from 0 to 1A. The circuit current consumption is specified at 0.6mA.
