Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for MC78M18CDTRK

MC78M18CDTRK

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

The MC78M18CDTRKG is a fixed positive linear voltage regulator from the MC78M00 series, manufactured by onsemi. It provides a nominal output voltage of 18 V with a maximum continuous output current of 500 mA. The device operates within an input voltage range up to 35 V and features an operating junction temperature range of 0°C to +125°C. Packaged in a surface-mount DPAK-3 (TO-252) case, it includes internal thermal overload protection and short-circuit current limiting.

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

Internal thermal overload protection shuts down the circuit during excessive power overload conditions.
Internal short-circuit current limiting protects the device under fault conditions.
Output transistor safe-area compensation reduces output 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 supply regulation

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

Verify the specific ordering suffix against official documentation to confirm package type and shipping configuration. Ensure the part number matches the required voltage option and temperature range specifications for your application design.

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

Select this component for applications requiring a fixed 18 V output at currents up to 500 mA. Consider the DPAK-3 package for surface-mount designs and ensure adequate heatsinking or PCB copper area is available to manage power dissipation within the specified thermal limits.

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

This device belongs to the MC78M00 series of three-terminal positive voltage regulators. It shares functional similarities with the MC7800 series but is rated for half the output current. The series is designed for rugged operation with integrated protection circuits suitable for local regulation tasks.
