L7806ACD2T-TR

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

The L7806ACD2T-TR is a fixed positive linear voltage regulator from the STMicroelectronics L78 series, housed in a D2PAK surface-mount package. It provides a fixed output voltage of 6V with a maximum continuous output current of 1.5A. The device supports an input voltage range up to 35V and operates within a junction temperature range of -40°C to +125°C. Key electrical characteristics include a typical dropout voltage of 2V at 1A load and a static current of approximately 8mA. Internal protection features include thermal overload shutdown and short-circuit current limiting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated thermal overload protection prevents damage during excessive heat conditions.
• Internal short-circuit current limiting safeguards the device against output faults.
• Fixed output voltage configuration eliminates external feedback components.

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

• General-purpose power supply regulation
• Local voltage regulation for logic circuits
• Battery-powered equipment power conditioning

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

Verify the specific suffix 'CD2T' matches the required D2PAK package variant and tape-and-reel orientation. Confirm that the 'AC' designation aligns with the intended operating temperature range specifications. Ensure compatibility with existing PCB footprint dimensions for the TO-263AB form factor before finalizing procurement orders.

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

Select this component when a robust, high-current (1.5A) fixed 6V source is required in a surface-mount format. Compare against L78Lxx series if lower current (100mA) suffices to reduce cost. Verify that the input voltage remains sufficiently above the output voltage to maintain regulation without exceeding the maximum rated input limit.

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

This part belongs to the industry-standard L78xx family of three-terminal positive regulators. It serves as a direct pin-compatible alternative to other manufacturers' equivalents like the MC7806. The D2PAK packaging facilitates efficient heat dissipation compared to smaller SOT packages, supporting higher current loads in compact designs.

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

Direct functional substitutes include the MC7806ACD2T-TR from ON Semiconductor/NXP and the LM7806 variants from Texas Instruments. Verify that replacement parts share the identical D2PAK pinout and thermal pad configuration to ensure mechanical interchangeability.
