MC7806BD2TR4G

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

The MC7806BD2TR4G is a monolithic integrated circuit positive linear voltage regulator from the MC7800 series, manufactured by onsemi. It provides a fixed nominal output voltage of 6 V with a maximum output current exceeding 1.0 A. The device utilizes a D2PAK-3 surface-mount package (TO-263-3) and incorporates internal thermal overload protection, short-circuit current limiting, and output transistor safe-area compensation. Designed for local on-card regulation, it requires no external components for basic operation.

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

• Integrated thermal overload protection shuts down the circuit during excessive power conditions
• Internal short-circuit current limiting protects against output faults
• Output transistor safe-area compensation reduces current as voltage across the pass transistor increases
• Fixed voltage regulation without requiring external feedback components

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

• Local on-card voltage regulation
• Positive voltage supply rails in electronic circuits
• Power management sections requiring fixed 6 V outputs

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

Verify the specific suffix BD2TR4G corresponds to the D2PAK-3 surface mount package and tape-and-reel shipping configuration. Confirm that the B suffix indicates the specified voltage tolerance class. Ensure the ordering part number matches the required automotive or industrial qualification status, as standard MC7800 variants may differ from NCV prefixed automotive qualified versions.

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

Select this component when a fixed 6 V output is required with currents up to 1.0 A in a surface-mount form factor. Consider the thermal resistance characteristics of the D2PAK-3 package and the necessity of adequate heatsinking for sustained high-current operation. Evaluate input-to-output voltage differentials to ensure power dissipation remains within the internally limited ratings under all operating conditions.

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

This device belongs to the MC7800 series of positive voltage regulators, which includes various fixed output voltages ranging from 5 V to 24 V. The series is characterized by robust internal protection features and compatibility with standard transistor packages. The MC7806 variant specifically targets applications needing a 6 V regulated rail, sharing the same functional architecture and protection mechanisms as other members of the family.

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

Direct pin-compatible replacements within the same series include MC7806CD2TG or MC7806BD2TG, depending on the required tolerance and packaging preference. Cross-brand equivalents such as LM7806 in TO-263 packages may offer functional similarity but require verification of electrical parameters and pinout compatibility.
