BA15DD0T

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

The BA15DD0T is a fixed output low-dropout (LDO) linear regulator manufactured by Rohm Semiconductor, designed for high-current applications with a maximum output current of 2A. It operates within an input voltage range of 3V to 25V and provides a fixed output voltage with ±1.0% accuracy at 25°C. The device features a typical dropout voltage of 0.45V at full load and offers a ripple rejection ratio of 55dB. Integrated protection circuits include thermal shutdown, over-current protection, and over-voltage protection. It is housed in a TO-220FP-3 package and supports an operating temperature range from -40°C to 125°C.

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

• Built-in thermal shutdown circuit protects the IC from damage due to overheating under overload conditions.
• Integrated over-current protection prevents destruction of the IC during output short circuits.
• Over-voltage protection ensures internal component safety against excessive input or transient voltages.
