Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for MC78M08CT

MC78M08CT

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

The MC78M08CT is a fixed positive voltage regulator from the MC78M00 series, manufactured by onsemi. It provides an output voltage of 8 V with a maximum output current of 500 mA. The device utilizes a TO-220 package and supports a maximum input voltage of 35 V. Line regulation is specified at 50 mV, while load regulation reaches 160 mV under full load conditions. The component operates within a junction temperature range of 0°C to +125°C.

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 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
Current boost applications using external transistors
Constant current source circuits

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

Verify the specific suffix 'CT' corresponds to the TO-220 package and standard operating temperature range (0°C to +125°C) in the official datasheet. Confirm RoHS compliance status for the exact manufacturing lot, as older revisions may differ. Ensure adequate heatsinking is planned, as the maximum output current of 500 mA requires sufficient thermal management to maintain operation within the specified junction temperature limits.

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

Select this component when a fixed 8 V supply is required with moderate current demands up to 500 mA. It serves as a lower-current alternative to the MC7800 series. Consider the TO-220 package for through-hole mounting and ease of heat dissipation. Verify that the input voltage remains within the 35 V maximum rating and that the dropout voltage requirements are met for the intended load current.

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

This device belongs to the MC78M00 series of three-terminal positive voltage regulators. The series is designed similarly to the popular MC7800 devices but is specified for half the output current. The MC78M08 variant specifically targets the 8 V output level, providing a rugged solution for local regulation tasks without requiring external components for basic operation.
