BA78M12FP-E2

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

The BA78M12FP-E2 is a fixed-output linear voltage regulator from the ROHM BA78M series, housed in a surface-mount TO-252-3 package. It provides a nominal 12V output with a maximum continuous current of 500mA. The device operates within an input voltage range of 14.5V to 27V and maintains an output accuracy of ±4.0%. Key electrical parameters include a circuit current of 4.5mA, a dropout voltage of 2V at full load, and a typical power supply rejection ratio (PSRR) of 63dB at 120Hz. It functions reliably across an operating temperature range of -40°C to +85°C.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be limited. Ensure the specific suffix matches required specifications before ordering. Request official datasheets to validate pinout and thermal performance data against your design requirements.

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

Select this component when a fixed 12V output is required with moderate current demands up to 500mA. The TO-252-3 package suits applications needing surface-mount assembly with adequate heat dissipation. Consider the input voltage headroom necessary to maintain regulation and account for thermal resistance in the final enclosure design to prevent overheating under high load conditions.

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

This part belongs to the BA78M series of 500mA linear regulators manufactured by ROHM Semiconductor. The series includes both through-hole (TO-220CP-3) and surface-mount (TO-252-3) variants. These regulators are designed as drop-in replacements for traditional 78-series devices, offering improved performance metrics while maintaining compatibility with standard regulatory frameworks and application notes.

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

Direct substitutes include other BA78M12FP-E2 units or equivalent 12V 500mA linear regulators in TO-252-3 packages. Verify pinout compatibility and thermal characteristics before swapping. Alternative series may require circuit adjustments due to differences in dropout voltage or current limits.
