概要

Description

MC78LC30NTRG is a fixed positive voltage regulator in the 78xx family that provides a steady +3.0 V output from a higher DC input, intended for low‑current circuitry (≈100 mA max).
Key points:
- Output: +3.0 V
- Input range: up to roughly 15–20 V (depends on variant)
- Dropout: about 0.5–1.0 V at full load
- Protection: short‑circuit and thermal shutdown; typical current limit
- Pinout (TO‑220, front view): left = Input, middle = Ground, right = Output
- External caps: usually input ≈ 0.33 µF; output ≈ 0.1 µF for stability
- Package: TO‑220 through‑hole; NTRG indicates packaging/ RoHS options per supplier
Use for simple, low‑power regulation where a stable 3.0 V is needed (e.g., microcontroller or sensor supply). Check the exact datasheet for precise electrical limits and recommended capacitors.

Features

MC78LC30NTRG is a fixed 3.0 V positive voltage regulator in a 3‑pin TO‑92 (NTRG) package. Key features:
- Fixed 3.0 V output
- Output current up to ~100 mA
- No external components required
- Internal current limiting and thermal shutdown
- Safe-area protection and short-circuit protection
- Wide input range (typical up to ~15 V)
- Operating temperature: -40°C to ~125°C
- Rugged, low-cost device suitable for general-purpose regulation

Package

TO-220 through-hole package. The NTRG suffix denotes Tape & Reel shipping (TR) with RoHS lead-free (G).

Pinout

- Pin count: 3
- Function: Fixed positive voltage regulator (outputs 3.0 V). Pins are Vin, Ground, Vout. In common TO‑220 packaging (and many variants), pin1 = input, pin2 = ground, pin3 = output.

Manufacturer

- Manufacturer: ON Semiconductor (originally Motorola).
- What kind of company: An American multinational semiconductor designer and manufacturer that produces ICs, discrete components, power management devices, and other semiconductor products.

Application

- Provide a stable 3.0 V supply for low-power digital logic and microcontrollers from a higher input (e.g., 5 V USB).
- Battery-powered portable devices (sensors, wearables, handheld meters) needing a compact 3 V rail.
- Small consumer electronics and hobbyist projects requiring a fixed 3 V regulator.
- Analog circuits bias/reference supplies (op-amps, ADCs) operating on 3 V.
- Prototyping and educational circuits needing a cheap, fixed 3 V regulator.
