Detailed Description

Fixed 5 V linear voltage regulator from the classic 78M05 family. Medium-current output suitable for powering 5 V logic and peripherals. Surface-mount DPAK TO-252 package for compact designs. Built-in protections for overcurrent and overtemperature. Simple two-capacitor application. Listed under Integrated Circuits and Specialized ICs. Stock available 2020 units.

Key Features

Fixed 5 V regulated output

Medium output current class for the 78M series

Wide input voltage range typical of 78xx regulators

Internal current limiting and thermal shutdown

Stable with standard input and output capacitors

Low noise compared with switching regulators

Simple, reliable, time-proven 78xx architecture

TO-252 DPAK surface-mount format

Tape and reel shipment for automated assembly

Key Advantages

Very easy to design in and debug

Low BOM cost and minimal external components

High robustness with built-in protections

Broad second-source availability across multiple brands

SMD package saves space versus TO-220 through-hole

Good line and load regulation for clean 5 V rails

Ideal when low noise and simplicity are more important than high efficiency

Packaging

Type TO-252 DPAK surface-mount

Material Molded epoxy body with copper leadframe and tin-plated leads

Size Compact DPAK footprint with a large thermal tab for heat spreading

Pin configuration 3 leads plus exposed tab. Typical 78M05 mapping Input, Ground, Output. Tab commonly tied to Ground. Always confirm orientation and pinout in the datasheet before layout

Tape and reel option DTR suffix indicates tape and reel packaging for pick-and-place

Thermal characteristics Exposed metal tab designed to solder to a copper pad for efficient heat dissipation. Performance depends on PCB copper area and thermal vias. Integrated thermal shutdown for protection

Electrical properties Positive fixed regulator set to 5 V output. Typical dropout in the 78M class is around a couple of volts under load. Good line and load regulation. Use recommended input and output capacitors close to pins for stability and transient response

Case code Manufacturer case identifier 755 as supplied

Lifecycle

Status Motorola-marked MC78M05CDTR is a legacy designation. The 78M05 family remains widely supported by multiple manufacturers. The exact Motorola suffix may be limited or discontinued, but active, form-fit-function equivalents are available
