ONMC78L05ABDR2G
Overview
The MC78L05ABDR2G is a fixed-output positive linear voltage regulator designed to deliver 5V at up to 100mA. It is a cost-effective solution for local on-card regulation, eliminating noise and distribution problems associated with single-point regulation. This 8-SOIC device includes internal thermal overload protection and short-circuit current limiting to ensure robust operation under fault conditions.
Why Choose This Part
The regulator requires no external components for basic operation, reducing PCB footprint and BOM complexity. It features a wide operating temperature range from -40C to 125C and a high maximum input voltage of 30V. Integrated protection features like thermal shutdown and internal current limiting make it highly resilient to circuit abuses.
Applications
Key Specifications
Getting Started
To implement this regulator, connect the input pin to a DC source between 7V and 20V for optimal performance, and the output pin to your 5V load. Although not strictly required by the internal design, it is best practice to place a 0.33uF ceramic capacitor on the input and a 0.1uF capacitor on the output to improve high-frequency response and stability. Ensure the SOIC-8 package has adequate copper area for heat dissipation if operating near the 100mA limit with high input-to-output voltage differentials.
