BAJ5CC0FP-E2

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

The BAJ5CC0FP-E2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It features a PNP output transistor architecture designed for low saturation voltage applications. The device provides a maximum output current of 1A with a typical dropout voltage of 0.3V at 0.5A load. It operates within an input voltage range of 4V to 25V and withstands up to 35V. The output voltage accuracy is ±2.0% at 25°C. Integrated protection circuits include thermal shutdown, over-current protection, and over-voltage protection. The component is housed in a TO252-3 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 E2 for RoHS compliance status during procurement. Confirm the TO252-3 package dimensions match your PCB footprint requirements. Ensure the fixed output voltage variant matches the system design needs as this model does not support adjustable outputs. Check for end-of-life notices if long-term availability is critical for production planning.

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

Select this component when a 1A current capacity with low dropout characteristics is required. The PNP output structure offers lower saturation voltage compared to standard NPN types. Verify that the input voltage does not exceed the 25V maximum rating. Consider the thermal performance in the TO252-3 package for high-load applications to ensure junction temperatures remain within safe limits.

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

This part belongs to the BAxxCC0FP series of 1A fixed output LDO regulators. The series is characterized by its robust protection features and low saturation voltage. It is distinct from variable output models like the BA50BC0FP which require external resistors. The TO252-3 package is commonly referred to as DPAK-3 in reference codes.

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

Direct substitutes within the same series include BA05CC0FP-E2 for 5V output or BA07CC0FP-E2 for 7V output, provided the voltage requirement differs. Cross-referencing with other manufacturers requires matching the 1A current rating, TO252-3 package, and PNP output topology.
