BA03T

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

The BA03T/FP is a fixed positive output low-dropout voltage regulator with a nominal 3.0V output. It supports a maximum output current of 1A and operates within an input voltage range of 4V to 25V. The device features a typical dropout voltage of 0.3V at 500mA and maintains an output accuracy of ±2%. Electrical characteristics include a ripple rejection ratio of 55dB and a bias current of 2.5mA. It utilizes a TO-220FP package with a power dissipation rating of 2W.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Built-in overvoltage protection circuit prevents damage from excessive input voltage.
• Integrated overcurrent protection limits output current to prevent IC destruction during short circuits.
• Thermal shutdown circuit activates when junction temperature exceeds safe limits, turning off outputs until cooling occurs.
