BA7805CP-E2

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

The BA7805CP-E2 is a linear voltage regulator from the BA78 series manufactured by ROHM Semiconductor. It provides a fixed positive output of 5 V at a maximum current of 1 A. The device operates within an input voltage range of 7.5 V to 25 V and supports a power dissipation of 22 W. It features a line regulation of 15 mV, load regulation of 37 mV, and a typical PSRR of 78 dB. The component is housed in a TO-220CP-3 package for through-hole mounting and functions reliably across an operating temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated overcurrent protection circuitry prevents damage during short-circuit or overload conditions.
• Built-in thermal shutdown circuit automatically turns off the regulator when excessive junction temperatures are detected.
• High ripple rejection capability ensures stable output voltage despite input supply noise.

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

• General-purpose DC power supply circuits requiring regulated 5 V outputs
• Embedded systems and microcontroller power conditioning

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

Verify RoHS compliance status and REACH SVHC declarations prior to procurement. Confirm that the TO-220CP-3 package matches the target PCB footprint and thermal design requirements. Ensure the supplier provides valid traceability documentation for this specific ROHM part number.

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

Select this component when a robust, high-current linear regulator with integrated thermal and current protection is required. The TO-220CP-3 package facilitates effective heat dissipation for up to 22 W power handling. Verify that the input voltage remains within the specified 7.5 V to 25 V range to maintain proper regulation.

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

This part belongs to the BA78 series of standard linear regulators produced by ROHM Semiconductor. It serves as the lead-free, environmentally compliant version of the legacy BA7805CP. The series is designed for general-purpose applications requiring reliable voltage regulation with built-in safety features.

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

The BA78M05CP-E2 is listed as a substitute option, though it offers a reduced output current of 500 mA compared to the 1 A rating of the BA7805CP-E2. Verify that the lower current capacity meets the application requirements before substitution.
