MC7824CTG

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

The MC7824CTG is a monolithic integrated circuit positive linear voltage regulator from the MC7800 series, manufactured by onsemi. It provides a fixed 24 V output with an output current capability exceeding 1.0 A. The device employs internal current limiting, thermal shutdown, and safe-area compensation to ensure reliable operation. Designed for local on-card regulation, it requires no external components for basic functionality. The component is available in standard three-lead transistor packages.

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 short-circuit current as voltage across the pass transistor increases

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

• Local on-card voltage regulation
• Fixed-voltage power supply applications
• General-purpose linear regulation requiring simple design

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

Verify the specific suffix 'C' indicates the standard tolerance grade when sourcing replacements. Confirm the package type matches the required through-hole mounting style. Ensure the manufacturer is identified as onsemi or its authorized predecessors. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate that the ordering part number corresponds exactly to the MC7824CTG designation.

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

Select this component when a fixed 24 V output is required with moderate current demands. Consider the thermal resistance characteristics for heatsinking requirements at full load. Evaluate input voltage ranges to ensure sufficient dropout voltage is maintained. Compare line and load regulation specifications against system stability needs. Verify compatibility with existing PCB footprint designs for the TO-220 package.
