L7806CV

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

The UMW L7806CV is a three-terminal positive linear voltage regulator in the L78xx series, housed in a TO-220 package. It provides a fixed output voltage of 6 V with a maximum output current of 1.5 A. The device accepts an input voltage range from 8 V to 35 V and operates within a temperature range of 0 °C to +125 °C. Internal protections include thermal shutdown, short-circuit protection, and safe operating area (SOA) limits.

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

Verify the manufacturer designation on the component marking, as the L7806CV part number is widely used by multiple semiconductor manufacturers including STMicroelectronics and UMW. Confirm the specific datasheet version matches the required electrical tolerances and thermal characteristics for your design. Ensure the TO-220 package pinout aligns with your PCB footprint requirements before finalizing procurement.

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

Select this component when a stable 6 V DC supply is required with up to 1.5 A load capacity. It is suitable for through-hole mounting where heat dissipation is managed via the tab. Consider the input-to-output voltage differential to ensure adequate heat sinking, as the device dissipates significant power under high load or large input voltage differences compared to low-dropout alternatives.

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

This component belongs to the L78xx family of standard linear regulators, known for their simplicity and reliability in fixed-voltage applications. The L7806 variant specifically targets 6 V output needs. While originally popularized by STMicroelectronics, UMW produces equivalent devices in the same form factor, maintaining compatibility with legacy designs requiring this specific voltage level and current capability.

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

Direct functional substitutes include LM7806, MC7806, and KA7806. These parts share identical pinouts and electrical specifications. Verify that any replacement maintains the same TO-220 package dimensions and thermal resistance values to ensure proper fit and heat dissipation in existing assemblies.
