BA178M15CP-E2

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

The BA178M15CP-E2 is a fixed linear voltage regulator from ROHM Semiconductor, delivering a stable 15 V output at up to 500 mA. It operates within an input voltage range of 17.5 V to 30 V and supports through-hole mounting in a TO-220CP-3 package. The device maintains line regulation at 10 mV and load regulation at 20 mV, with a typical power dissipation capacity of 22 W. It functions reliably across temperatures from -40°C to +85°C and includes internal overcurrent and thermal shutdown protection.

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

• Integrated overcurrent protection circuitry prevents damage during short-circuit or overload conditions.
• Thermal shutdown mechanism automatically disables the output when junction temperature exceeds safe limits.
• High ripple rejection characteristics ensure clean DC output despite input noise variations.

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

• General-purpose positive voltage regulation in industrial control systems
• Power supply stages for embedded microcontroller circuits requiring 15 V rails
• Analog signal conditioning modules needing stable bias voltages

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

Verify component authenticity via manufacturer serial codes and datasheet cross-references. Confirm RoHS compliance status before integration. Check current lifecycle status as end-of-life notices may affect long-term availability. Validate package pinout compatibility with existing PCB footprints. Ensure thermal management design accounts for 22 W dissipation capability under worst-case load conditions.

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

Select this regulator when a fixed 15 V output at 500 mA is required with robust protection features. The TO-220CP-3 package suits applications needing efficient heat dissipation without active cooling. Consider input voltage headroom requirements between 17.5 V and 30 V. Evaluate thermal resistance paths if operating near maximum ambient temperature limits. Compare line and load regulation specs against downstream circuit sensitivity requirements.

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

This component belongs to ROHM’s BA178M series of medium-current linear regulators. It shares architectural similarities with other members like BA178M05CP-E2 and BA178M24CP but differs in fixed output voltage. The series targets cost-sensitive designs requiring reliable regulation without complex external feedback networks. Packaging options include both through-hole and surface-mount variants across the family.

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

Publicly confirmed substitute part numbers are not available in verified documentation. Cross-reference only with identical BA178M15CP-E2 units or manufacturer-approved equivalents listed in official replacement guides. Avoid generic 7815 replacements unless electrical parameters and pinouts match exactly.
