L7805ABV-DG

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

The L7805ABV-DG is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series, providing a stable 5 V output with a maximum load current of 1.5 A. It operates within an input voltage range up to 35 V and maintains a typical quiescent current of 4.3 mA. The device features high line regulation of 50 mV and load regulation of 100 mV, ensuring precise voltage control under varying conditions. It is housed in a TO-220-3 through-hole package and supports an operating temperature range from -40 °C to +125 °C.

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 electronic circuits
• Local on-card regulation for distribution systems
• Power supply units requiring fixed 5 V outputs

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