BA80JC5T

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

The BA80JC5T is a fixed-output low-dropout (LDO) regulator from ROHM Semiconductor, designed for secondary power supply applications. It delivers a maximum output current of 1.5 A with a voltage accuracy of ±1.0% at 25°C. The device features a typical dropout voltage of 0.3 V at 0.5 A and operates within an input voltage range of 9 V to 16 V, with a maximum withstand voltage of 18 V. It includes built-in thermal shutdown and overcurrent protection circuits. The component is housed in a TO220FP-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 'T' corresponds to the tube packaging format as documented in official ROHM datasheets. Confirm that the part status is listed as 'Last Time Buy' or similar end-of-life designation if applicable to current procurement cycles. Ensure compatibility with TO220FP-3 mounting requirements and verify RoHS compliance documentation matches the specific manufacturing batch.

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

Select this component when a fixed output voltage near 8.0 V is required with high current capability up to 1.5 A. The low dropout characteristic makes it suitable for applications where the input voltage margin is limited. Consider the thermal performance in the TO220FP-3 package for heat dissipation needs. Verify that the fixed output option meets the system design without requiring external adjustment resistors.

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

The BA80JC5T belongs to the BA□□JC5 series of secondary LDO regulators. This series offers broad output voltage options ranging from 1.5 V to 12 V. The 'JC5' designation indicates a fixed-output variant with PNP output stage technology. It is distinct from the WT variants which include integrated shutdown switches. The series is engineered for robustness in secondary power conversion tasks.

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

The BA25JC5T and BA15JC5T are alternative parts within the same BA□□JC5 series offering different fixed output voltages but sharing identical 1.5 A current capacity, TO220FP-3 packaging, and protection features. These substitutes maintain pinout compatibility and electrical characteristics except for the regulated output voltage level.
