BA78M15FP-E2

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

The BA78M15FP-E2 is a fixed linear voltage regulator from the ROHM BA78M series, housed in a TO-252-3 surface-mount package. It provides a fixed positive output of 15 V with a maximum load current of 500 mA. The device operates within an input voltage range of 14.5 V to 27 V and supports a junction temperature range from -40 °C to +85 °C. Key electrical specifications include a line regulation of 6 mV, load regulation of 20 mV, and a typical power supply rejection ratio (PSRR) of 60 dB. The component features internal overcurrent protection and thermal shutdown circuits.

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

• Integrated overcurrent protection circuit 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 noise variations.

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

• General-purpose positive voltage regulation in electronic circuits
• Power management for low-current embedded systems
• Voltage conditioning for sensor interfaces requiring 15 V rails

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific batch. Check for alternative packages like BA78M15CP-E2 if through-hole mounting is required. Ensure design accounts for thermal dissipation limits inherent to the TO-252-3 package under specified load conditions.

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

Select this component for applications requiring a fixed 15 V output at up to 500 mA in a compact surface-mount form factor. Consider the TO-252-3 package constraints regarding thermal performance compared to larger packages. Evaluate input voltage headroom requirements against the minimum 14.5 V specification. Verify that the 60 dB PSRR meets system noise sensitivity requirements.
