BA78M05CP-E2

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

The BA78M05CP-E2 is a fixed linear voltage regulator from the ROHM BA78M series, providing a stable 5 V output with a maximum current capacity of 500 mA. It operates within an input voltage range of 7.5 V to 25 V and features a TO-220CP-3 through-hole package. The device includes internal overcurrent protection and thermal shutdown circuits for reliability. Key electrical specifications include a line regulation of 10 mV, load regulation of 20 mV, and a typical power supply rejection ratio (PSRR) of 78 dB at 120 Hz. It supports a maximum power dissipation of 22 W and functions across a 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 mechanism automatically disables the output when excessive junction temperatures are detected.
• High ripple rejection capability ensures clean output voltage stability against input noise fluctuations.

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

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

Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm RoHS compliance status as indicated in official documentation. Ensure the TO-220CP-3 package matches design requirements. Check for end-of-life status updates directly from ROHM Semiconductor before finalizing procurement plans.

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

Select this regulator when a fixed 5 V output is required with moderate current demands up to 500 mA. The TO-220CP-3 package suits applications allowing through-hole mounting and adequate heat sinking. Consider the 7.5 V minimum input requirement and ensure sufficient headroom for desired load currents to maintain regulation.

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

This component belongs to the BA78M series of linear regulators manufactured by ROHM Semiconductor. It is part of the broader PMIC category, specifically designed for voltage regulation tasks. The 'E2' suffix typically denotes environmental compliance variations, though functional parameters remain consistent with the base BA78M05 model family.
