L78M05CV-DG

Overview

The L78M05CV-DG is a three-terminal positive linear voltage regulator from the L78Mxx series, manufactured by STMicroelectronics. It provides a fixed 5 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range up to 35 V and supports junction temperatures up to +150 °C. Key electrical parameters include a typical PSRR of 62 dB at 120 Hz, line regulation of 100 mV, and load regulation of 100 mV. It features internal thermal overload protection, short-circuit protection, and safe area protection.

Feature Summary

Provides local on-card regulation for stable 5 V DC power delivery
Integrates comprehensive protection against thermal overload, short circuits, and safe area operation
Delivers up to 500 mA output current in a through-hole TO-220 package

Applications

General-purpose power supply regulation
Local on-card voltage regulation
Battery chargers
Off-line converters

Procurement Notes

Verify the specific suffix 'DG' against official STMicroelectronics documentation to confirm exact packaging or material compliance details, as standard datasheets may list 'L78M05CV'. Ensure the required 500 mA current rating aligns with thermal management capabilities in the final application design.

Selection Notes

Select this component when a fixed 5 V output with moderate current capability (500 mA) is required. It serves as a cost-effective solution for applications needing robust internal protection features. Consider the TO-220 package for adequate heat dissipation without external components under normal operating conditions.

Part Context

This part belongs to the L78Mxx series of three-terminal positive regulators, distinct from the higher-current L7805 series. It is designed for industrial and commercial applications requiring reliable voltage regulation in a compact form factor. The device eliminates distribution problems associated with single-point regulation by providing localized power control.
