BA25BC0FP-E2

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

The BA25BC0FP-E2 is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It provides a stable 2.5V output with a maximum continuous current of 1A and an accuracy of ±2.0% at 25°C. The device operates within an input voltage range of 3.5V to 16V, featuring a typical dropout voltage of 0.3V at 0.2A load. Key electrical characteristics include a ripple rejection of 55dB and a circuit current of 0.5mA. It incorporates thermal shutdown and overcurrent protection, functions without a shutdown pin, and requires a 22µF output capacitor. The component is housed in a TO-252-3 package and supports an operating temperature range from -40°C to +105°C.

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

Verify the specific suffix E2 to confirm RoHS compliance and lead-free status. Confirm the TO-252-3 package type matches your PCB footprint requirements. Check official documentation for current lifecycle status, as this model may be subject to discontinuation notices. Ensure the required 22µF output capacitor specification is included in your bill of materials for proper stability.

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

Select this component when a fixed 2.5V rail is required with 1A capacity. The low dropout characteristic suits applications where input voltage is close to the output level. Verify that the absence of a shutdown function aligns with system control logic. Consider the thermal performance in the TO-252-3 package relative to expected ambient temperatures and heat dissipation constraints.
