L78LR05E-MA-E

Overview

The L78LR05E-MA-E is a linear voltage regulator IC manufactured by onsemi. It provides a fixed 5V output with a maximum current capacity of 150mA. The device accepts input voltages up to 20V and utilizes the TP5HFA package for surface-mount installation. This component belongs to the linear regulator category within power management integrated circuits.

Feature Summary

• Provides a stable fixed 5V DC output voltage
• Supports continuous load currents up to 150mA
• Operates with input supply voltages ranging up to 20V

Applications

• General-purpose linear voltage regulation in electronic circuits
• Power management modules requiring 5V logic levels
• Embedded systems utilizing surface-mount assembly processes

Procurement Notes

Verify the specific TP5HFA package designation when sourcing, as it differs from standard through-hole variants. Confirm end-of-life status or availability constraints directly with authorized distributors, as discontinuation notices may affect long-term supply chain stability for this specific marking code.

Selection Notes

Select this component when a compact surface-mount solution is required for low-current 5V regulation. Ensure the application design accommodates the thermal dissipation limits inherent to linear regulators operating with significant input-output voltage differentials at 150mA loads.

Part Context

This part is part of onsemi's portfolio of linear voltage regulators. It serves as a surface-mount alternative to traditional through-hole packages like TO-220 or TO-92, offering similar electrical performance in a form factor suitable for automated PCB assembly and space-constrained designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct pin-to-pin replacements such as other 150mA 5V SMD linear regulators only after confirming package and thermal specifications match.
