L7805ACV-DG

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

The L7805ACV-DG is a three-terminal positive linear voltage regulator from the STMicroelectronics L78 series, housed in a TO-220-3 through-hole package. It provides a fixed 5 V output with a maximum current capability of 1.5 A. The device features a line regulation of 50 mV and load regulation of 100 mV. It operates within an ambient temperature range of 0 °C to +125 °C and includes internal thermal overload protection, short-circuit protection, and output safe-area compensation.

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

• Integrated thermal overload protection that shuts down the circuit during excessive power overload conditions.
• Internal short-circuit protection limits the maximum current passed by the circuit.
• Output transistor safe-area compensation reduces output short-circuit current as voltage across the pass transistor increases.

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

• Local on-card voltage regulation
• General-purpose power supply circuits
• Embedded system power management

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

Verify the specific suffix 'DG' against the manufacturer's official datasheet to confirm compliance with RoHS directives and packaging specifications. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability for industrial-grade applications.

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

Select this component when a robust, high-current (up to 1.5 A) fixed 5 V source is required in a through-hole format. The 'A' grade designation indicates tighter output voltage tolerance compared to standard variants. Consider the TO-220 package's thermal dissipation capabilities relative to the expected power loss in the application environment.

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

This part belongs to the L78xx family of three-terminal positive regulators, designed for eliminating distribution problems associated with single-point regulation. The L78 series is widely used for local on-card regulation, offering reliability through embedded protection features such as current limiting and thermal shutdown without requiring external components.

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

Compatible substitutes include the L7805CV and L7805ABV, which share the same pinout and functional characteristics within the L78 series. Verify that alternative packages match the thermal requirements and physical footprint constraints of the existing design.
