L7805CV-DG

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

The L7805CV-DG is a three-terminal positive linear voltage regulator from the STMicroelectronics L78xx series, designed for local on-card regulation. It provides a fixed 5 V output with a maximum continuous current of 1.5 A and supports input voltages up to 35 V. The device features thermal overload protection, short-circuit protection, and output transition safe operating area (SOA) protection. It operates within an extended temperature range from 0 °C to +125 °C and utilizes a TO-220 package.

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

Verify the specific suffix DG against official datasheets to confirm packaging details and compliance status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the part number with the latest product documentation to confirm availability and any potential obsolescence notices before finalizing orders.

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

Select this component when a robust, high-current 5 V linear regulator is required for industrial applications. The TO-220 package facilitates effective heat dissipation for currents up to 1.5 A. Consider the 125 °C maximum operating temperature limit for environmental suitability. Verify that the input voltage remains within the 35 V absolute maximum rating to ensure reliable operation.

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

This component belongs to the widely used L78xx family of three-terminal positive regulators. The L7805 variant specifically delivers a fixed 5 V output. The L7805CV-DG designation indicates the standard commercial grade version housed in a TO-220 package, distinct from the higher precision AC versions or lower current M-series variants within the same product line.

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

Compatible substitutes include other manufacturers' equivalents such as MC7805CT or LM7805CT. Ensure the replacement maintains the TO-220 pinout configuration and matches the 1.5 A current capability. Verify that the substitute also offers comparable thermal and short-circuit protection features.
