BA25DD0T

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

The BA25DD0T is a fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 2.5V output with a maximum load current of 2A. The device operates within an input voltage range of 3V to 25V and withstands up to 35V. Key electrical specifications include a typical dropout voltage of 0.45V at full load, output accuracy of ±1.0% at 25°C, and ripple rejection of 55dB. It features thermal shutdown, over-current protection, and over-voltage protection. The component 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 Procurement Notes

Verify the specific suffix and packaging configuration against the official ROHM datasheet before ordering. Confirm that the TO-220FP-3 package matches your thermal and mechanical design requirements. Ensure compatibility with your system's input voltage range and load current demands. Check for any recent lifecycle status updates or alternative recommendations from the manufacturer.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.5V output is required with up to 2A continuous current capability. It is suitable for applications where low dropout performance is critical. Consider the TO-220FP-3 package for adequate heat dissipation. Verify that the input voltage does not exceed the 35V withstand limit. Ensure the application environment stays within the specified -40°C to 125°C operating temperature range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The BA25DD0T belongs to the BAxxDD0T series of 2A fixed-output LDO regulators from ROHM. This series shares common architectural features including similar protection mechanisms and package options. Other variants in the family offer different fixed output voltages while maintaining the same current handling and protection capabilities. The series is designed for robust performance in industrial and commercial applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Cross-reference with other BAxxDD0T variants if a different output voltage is needed. Verify pinout and thermal characteristics match when substituting with similar 2A LDO regulators from other manufacturers. Ensure the replacement part meets the same 35V withstand voltage and protection feature requirements.
