L7805ABV

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

The L7805ABV is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series, housed in a TO-220-3 through-hole package. It provides a nominal output voltage of 5 V with a maximum output current capability of 1.5 A. The device supports an input voltage range up to a maximum of 35 V and operates within a temperature range of -40 °C to +125 °C. Internal protections include thermal overload shutdown and internal short-circuit current limiting.

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

• General-purpose DC-to-DC conversion for regulated power supplies
• Local on-card regulation for distributed power systems
• Power management in embedded electronic circuits requiring stable 5 V rails

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

Verify the specific suffix 'BV' against the manufacturer's official datasheet to confirm pinout orientation and exact electrical tolerances. Ensure the procurement channel provides documentation confirming RoHS compliance and lead-free status. Cross-reference the part number with the latest STMicroelectronics release notes to verify active lifecycle status 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 (up to 1.5 A) linear solution is required for 5 V applications. The TO-220-3 package facilitates effective heat dissipation for higher load currents compared to smaller surface-mount variants. Consider the dropout voltage characteristics under full load to ensure sufficient input-output differential is maintained for proper regulation.

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

This component belongs to the L78xx family of three-terminal positive linear regulators manufactured by STMicroelectronics. The 'A' designation typically indicates tighter tolerance specifications compared to standard grades, while the 'B' suffix often denotes specific packaging or testing variations. The L78 series is widely recognized for its reliability and simplicity in basic voltage regulation tasks.

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

Compatible substitutes include the L7805CV and L7805CT from STMicroelectronics, which share similar functionality but may differ in package type or operating temperature ranges. Other manufacturers offer equivalent parts such as the LM7805, though pinouts and absolute maximum ratings should be verified for interchangeability.
