BA33BC0WT

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

The BA33BC0WT is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor, designed for local power supply applications. It delivers a maximum output current of 1A with an output voltage accuracy of ±2.0% at 25°C. The device operates within an input voltage range of 4.3V to 16V and withstands up to 18V. Key electrical parameters include a typical dropout voltage of 0.3V at 0.2A output, a ripple rejection of 55dB, and load regulation of 35mV from 0 to 1A. It requires a 22µF output capacitor and functions within a temperature range of -40°C to 105°C.
