L7805ACV

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

The L7805ACV is a three-terminal positive linear voltage regulator from the STMicroelectronics L78xx series, housed in a TO-220-3 through-hole package. It provides a fixed 5 V output with a maximum current of 1.5 A and an input voltage range up to 35 V. The device features a line regulation of 50 mV and load regulation of 100 mV. Operating temperatures span from 0°C to +125°C, with a typical static current of 4.3 mA and power supply rejection ratio (PSRR) of 68 dB at 120 Hz.

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 regulation for electronic circuits
• General-purpose power supplies requiring fixed 5 V output
• Battery chargers

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

Verify the specific suffix 'CV' against the manufacturer's official datasheet to confirm the exact package variant and temperature grade. Ensure the procurement documentation explicitly states compliance with RoHS standards. Confirm the component status is active or obsolescence notices are reviewed prior to finalizing orders.

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

Select this component when a robust, fixed 5 V source is required for industrial applications operating up to 125°C. The TO-220 package facilitates effective heat dissipation for currents approaching 1.5 A. Verify that the input voltage remains within the 35 V maximum limit to ensure proper regulation and device safety.

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

This part belongs to the L78xx family of three-terminal positive regulators designed for local on-card regulation. The 'A' designation indicates a tighter 2% output voltage tolerance compared to standard variants. The series eliminates distribution problems associated with single-point regulation by providing stable voltage directly at the load.

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

The UA7805CKCS from Texas Instruments is listed as a substitute part number. Verify pinout compatibility and thermal performance characteristics before implementing any cross-manufacturer replacement in existing designs.
