MC7805CTG

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

The MC7805CTG 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 exceeding 1.0 A. The device accepts an input voltage range of 7 V to 35 V and operates within a junction temperature range of 0°C to +125°C. It utilizes a TO-220 package for through-hole mounting, featuring internal thermal overload protection, short-circuit current limiting, and safe-area compensation.

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

• Internal 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

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

• Local on-card regulation
• Positive voltage regulation in power supplies
• Applications requiring fixed 5 V output

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

Verify the specific suffix 'C' indicates the standard 4% tolerance variant when ordering. Confirm the 'T' suffix corresponds to the TO-220 package style required for your assembly process. Ensure the component meets RoHS compliance standards if applicable to your manufacturing requirements.

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

Select this component for designs requiring a robust, high-current positive linear regulator. The TO-220 package facilitates effective heat dissipation for currents above 1.0 A with adequate heatsinking. Consider the dropout voltage requirements relative to your input supply ripple to ensure stable regulation under all operating conditions.
