MC7805BDT

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

The MC7805BDT is a monolithic integrated circuit fixed-voltage linear regulator from the MC7800 series by onsemi. It provides a nominal 5 V output with a maximum continuous current of 1.0 A. The device utilizes the D2PAK-3 surface-mount package and supports a maximum input voltage of 35 V. Electrical characteristics include internal thermal overload protection, short-circuit current limiting, and output transistor safe-area compensation. The component operates within a junction temperature range up to +150 °C.

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 short-circuit current as voltage across the pass transistor increases.

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

• Local on-card voltage regulation
• Positive voltage regulation for electronic circuits

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

Verify the specific suffix 'DT' corresponds to the D2PAK-3 surface-mount package configuration in official documentation. Confirm that the B grade designation aligns with required tolerance specifications. Ensure the ordering information matches the intended automotive or industrial site requirements if applicable.

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

Select this component when a fixed 5 V supply is required with up to 1 A load capacity in a surface-mount form factor. Consider the thermal resistance values for heatsinking requirements at higher input-output differentials. Verify compatibility with standard common ground configurations between input and output terminals.

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

This part belongs to the MC7800 series of positive voltage regulators, which also includes variants like MC7805BTG and NCV7805B. The series is designed for general-purpose fixed-voltage applications. The MC7805BDT specifically denotes the 5 V output version in the D2PAK-3 package, distinguishing it from through-hole or other tolerance grades within the same family.

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

Direct substitutes may include other MC7805 variants such as MC7805CD2TG or MC7805BD2TG, provided the package type and electrical tolerances match the design requirements. Cross-referencing with other manufacturers' 7805 series devices requires verification of pinout and thermal characteristics.
