L7806ABV-DG

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

The L7806ABV-DG is a positive fixed linear voltage regulator from the STMicroelectronics L78 series, housed in a TO-220 package. It provides a stable 6 V output with a maximum load current of 1.5 A. The device supports an input voltage up to 35 V and operates within a temperature range of 0°C to 125°C. Key electrical characteristics include a typical quiescent current of 4.3 mA, line regulation of 60 mV, and load regulation of 100 mV. It features internal thermal overload protection, short-circuit protection, and safe operating area (SOA) protection.

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

Verify the specific suffix 'DG' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the package type matches the required PCB footprint, typically TO-220. Check the lifecycle status, as some variants may be obsolete or end-of-life. Ensure the input voltage does not exceed the absolute maximum rating to prevent damage.

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

Select this component when a fixed 6 V output is required with up to 1.5 A load capability. Consider the thermal dissipation requirements due to the linear regulation topology. Verify that the input voltage remains within the specified limits relative to the output voltage to maintain proper regulation. Compare alternative packages if space constraints differ from the TO-220 form factor.

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

This part belongs to the L78 series of positive voltage regulators, widely used for their simplicity and reliability.
