BA25BC0WFP-E2

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

The BA25BC0WFP-E2 is a 1A variable/fixed output LDO regulator in a TO252-5 package. It features a maximum withstand voltage of 18V, with an input voltage range of 3.5V to 16V. The fixed output voltage accuracy is ±2.0% at 25°C. Typical dropout voltage is 0.3V at Io=0.2A. Ripple rejection is 55dB, and load regulation is 35mV from 0 to 1A. A 22µF output capacitor is required. Quiescent current is 0.5mA. Operating temperature ranges from -40°C to 105°C. It includes shutdown, thermal shut-down, and over-current protection.

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

Verify the specific suffix E2 matches the required RoHS compliance and tape-and-reel packaging configuration. Confirm the TO252-5 (PPAK-5) footprint compatibility with your PCB design. Check the datasheet for the latest status, as this component may be subject to discontinuation notices or end-of-life restrictions depending on the manufacturing date code.

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

Select this regulator when a 1A output current is necessary with a fixed voltage setting. Ensure the input voltage stays within the 3.5V to 16V range. Consider the 0.3V typical dropout voltage for efficiency. Verify that the 22µF output capacitor requirement fits your board space. Compare against other BAxxBC0 variants if different voltage accuracies or packages are needed.

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

This part belongs to the BAxxBC0 series of low-saturation regulators by ROHM Semiconductor. These devices are designed for applications requiring high current handling with minimal voltage loss. The series offers various fixed output voltages ranging from 1.5V to 10V. The BA25BC0WFP-E2 specifically provides a 2.5V fixed output option within this family.

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

BA25BC0FP-E2 is a similar 1A LDO but uses a TO252-3 package instead of TO252-5. Ensure pinout and thermal pad configurations match before substitution. Other BAxxBC0 series parts may offer different output voltages or protection features.
