L7805CV

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

The UMW L7805CV is a three-terminal positive linear voltage regulator in the L78xx series, housed in a TO-220-3 through-hole package. It provides a fixed 5V output with a maximum current of 1.2A. The device accepts an input voltage range from 7V to 35V and operates within a temperature range of -40°C to +105°C. Key electrical specifications include a typical static current of 6mA, line regulation of 100mV, load regulation of 100mV, and a power supply rejection ratio (PSRR) of 62dB at 120Hz.

• Fixed 5V output capability ensuring stable voltage delivery under varying load conditions
• Robust TO-220-3 through-hole packaging designed for efficient heat dissipation

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

• General-purpose power supply circuits requiring stable 5V DC rails
• Local on-card voltage regulation for logic systems
• Power management in embedded electronic devices

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

Verify the manufacturer designation as UMW rather than STMicroelectronics when sourcing this specific part number. Confirm the package type is TO-220-3 and the output current rating is 1.2A, as these parameters may differ from other manufacturers' equivalents. Ensure compliance with RoHS3 standards if required by your assembly specifications.

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

Select the L7805CV when a fixed 5V output is required with up to 1.2A load capacity in a through-hole configuration. Consider the 7V minimum input requirement and ensure adequate heatsinking for high differential voltages or currents near the 1.2A limit. Compare against the 78M05 for surface-mount needs or higher efficiency requirements.

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 UMW. It serves as a direct functional equivalent to industry-standard 7805 regulators but is distinguished by its specific manufacturer origin and 1.2A current rating in the TO-220 package. The series is widely used for basic voltage regulation tasks in consumer and industrial electronics.

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

The UM7805CT or similar UMW variants may serve as substitutes. Cross-reference with STMicroelectronics L7805CV for pin-compatible alternatives, noting potential differences in current ratings (1.5A vs 1.2A) and operating temperature ranges.
