BA70BC0T

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

The BA70BC0T is a fixed-output low-dropout (LDO) linear regulator from the BA series, designed for local power supply applications. It delivers a maximum output current of 1 A with a fixed output voltage accuracy of ±2.0% at 25°C. The device operates within an input voltage range of 8 V to 16 V and withstands up to 18 V. Key electrical characteristics include a typical dropout voltage of 0.3 V at 0.2 A load, 55 dB ripple rejection, and 35 mV load regulation across the full current range. It requires a minimum 22 µF output capacitor and functions reliably in temperatures from -40°C to 105°C.
