概述

Description

MC78M15CDTG is a fixed positive voltage regulator (part of the MC78Mxx family) that provides a regulated +15 V output. It can deliver up to about 1.5 A (with proper heatsinking). Key specs: Vin up to ~35 V, dropout ≈2 V at full load, and it includes thermal shutdown and current-limit protection. Pinout (TO-220, front view): 1 = Input, 2 = Ground, 3 = Output. It requires input and output decoupling for stability (typical: 0.33 μF at input and 0.1 μF at output; larger capacitors may be used for stability and transient response). Power dissipation is (Vin − 15 V) × Iout, so heat sinking may be necessary. Common uses: +15 V rails in power supplies and embedded systems, as a drop-in alternative to LM7815 in many circuits. Packaging suffix DG usually denotes TO-220 package with specific packaging (e.g., tape-and-reel); verify the exact packaging on the datasheet.

Features

Concise features of MC78M15CDTG:
- Fixed 15 V positive regulator, TO-220 (DTG) package
- Output current capability: up to about 1.5 A
- Internal current limit and thermal/shutdown protection
- Safe-operating-area protection
- Requires external capacitors for stability (typ. 0.33 µF input, 0.1 µF output)
- Input voltage range up to ~30 V (max ratings per datasheet)
- Dropout around 2 V (typical)
- Good line and load regulation
- Wide operating temp range (-40°C to +125°C)
- Pb-free/lead-free package version (CDTG)
Note: Values depend on the exact lot/specification; consult the datasheet for precise limits.

Package

TO-220AB through-hole package (three leads; Pb-free variant).

Pinout

Pin count: 3 pins.
Function: Fixed positive voltage regulator (three-terminal) that provides +15 V output (input, ground, output). In standard TO-220 front view, pins are typically IN, GND, OUT.

Manufacturer

- Manufacturer: ON Semiconductor (ON Semiconductor Corp.), an American multinational semiconductor company (the former Motorola Semiconductor division).
- What kind of company: A global chip maker that designs and manufactures semiconductors and power-management/discretes for automotive, industrial, consumer, and communications markets.

Application

MC78M15CDTG is a 15 V fixed linear regulator (up to about 0.5 A). It provides a simple, rugged, low-noise 15 V rail from higher inputs. Applications: inexpensive 15 V supplies for microcontrollers, analog front-ends, op-amps, ADC/DAC references; audio/video and instrumentation equipment; industrial controls/automation; automotive subsystems; educational labs and bench power supplies. Use proper input/output capacitors per the datasheet.

Equivalent

Equivalents (15 V fixed regulators, similar current and package):
- LM7815 (TI/National)
- L7815/L78M15 (ST)
- KA7815 (Renesas/NXP lineage)
- NCP7815 (Onsemi)
In practice, any 15 V fixed 78xx regulator with the same pinout (TO-220) and similar current rating can substitute.
