概述
Description
NJM7815FA is a fixed +15 V positive linear regulator from New Japan Radio (NJR), part of the NJM78xx family. It provides a stable +15 V output from a higher DC input.
Key points:
- Function: regulates a higher input down to +15 V for circuits.
- Output: typically up to ~1 A (depends on package/heat sinking); dropout around 2 V; max input ~30–35 V.
- Protections: overcurrent/short-circuit protection and thermal shutdown.
- Pinout (front view): Input – Ground – Output (tabs usually tied to Output; verify exact variant).
- Stability: requires input and output capacitors close to the pins (typical: 0.33 µF input, 0.1 µF output).
- Applications: general-purpose power supplies needing a +15 V rail.
Note: Always check the latest NJR datasheet for exact electrical specs, pinout, and packaging variants of NJM7815FA.
