概述

Description

NJM7815FA is a fixed positive 15‑volt linear voltage regulator from New Japan Radio (NJR), the NJR equivalent of the LM7815 in the 78xx family.
Key points:
- Output: +15 V (fixed); standard current up to about 1 A (with proper heat sinking).
- Input range: up to about 35 V (typical for 78xx parts); dropout around 2 V at rated current.
- Protection: thermal shutdown and current limiting to prevent damage.
- Pinout (TO‑220/3-pin package, common variant): Pin 1 = Input, Pin 2 = Ground, Pin 3 = Output. Check your specific package/datasheet.
- Stability: requires input and output capacitors for proper regulation (typical: ~0.33 µF input and ~0.1 µF output; larger capacitance may improve transient response).
- Packaging: available in TO‑220/TO‑220FA style variants.
- Applications: provides a stable 15 V rail for analog/digital circuits, op-amps, microcontrollers, and as a local regulator in power supplies.
Equivalent: LM7815. Always consult the specific datasheet for exact electrical specs and package options.

Features

NJM7815FA is a fixed 15‑V positive voltage regulator. Key features include:
- Fixed output: 15 V
- Output current: up to about 1.5 A
- Protection: internal current limit, thermal shutdown (overload/overtemp), safe‑area protection
- Regulation: good line and load regulation; low output ripple
- Stability: stable with appropriate input and output capacitors
- dropout: typical around 2 V at full load
- Protection diodes: inherent protection against brief reverse conditions
- Package availability: standard formats (e.g., TO‑220/SMD variants)
Note: exact electrical specs (max input voltage, precise current rating, dropout, etc.) are in the datasheet for the specific lot/package.

Package

TO-220 (through-hole) package.

Pinout

- Pin count: 3 pins
- Function: Fixed positive voltage regulator that outputs +15 V
- Pinout (typical): Pin 1 = Input, Pin 2 = Ground, Pin 3 = Output (TO-220/FA package)

Manufacturer

- Manufacturer: New Japan Radio Co., Ltd. (NJR, NJRC)
- Company type: A Japanese electronics and semiconductor company that designs and manufactures analog ICs and power-management devices (e.g., voltage regulators, op-amps, RF components) for industrial and consumer electronics.

Application

NJM7815FA is a fixed +15 V linear regulator. Typical applications:
- Fixed +15 V power rails for analog and digital circuits
- Op-amps, ADC/DAC front ends, instrumentation
- Microcontrollers, microprocessors, and FPGA peripheral supplies
- Audio equipment and preamplifier stages
- Industrial control and automation circuits
- General lab/test equipment requiring a stable +15 V with adequate heatsinking

Equivalent

Equivalents to NJM7815FA (15V fixed regulator) include 15V 78xx variants such as LM7815/LM7815CV, MC7815, KA7815, L7815/L7815CV, NTE7815 (and other 78xx clones). In SMD form, AMS1117-15 (SOT-223) is also common. Note pinout and dropout vary by package; check the specific datasheet.
