NJM7805FA

Product Overview

The NJM7805FA from Nisshinbo Micro Devices Inc. is a positive fixed-output linear voltage regulator. It provides a single 5V output at up to 1.5A, with a maximum input voltage of 35V. The device is supplied in a through-hole TO-220F package, listed as TO-220-3 Full Pack, and is listed as Active. Its specified operating temperature range is -40°C to 85°C. Quiescent current is 6 mA, and PSRR is 78dB at 120Hz. Over-temperature and short-circuit protection are included.

Applications

• 5V power rail for digital logic and microcontroller-based boards
• Point-of-load regulation from a higher DC input voltage within the 35V input limit
• Fixed 5V regulation in through-hole prototype, educational, or service boards

Design & Procurement Notes

Designers should account for the fixed 5V output and 1.5A current rating when defining load requirements. Because this is a linear regulator, the difference between input and output voltage can produce heat, especially near the rated current, so thermal layout and mounting provisions should be reviewed. The 35V maximum input voltage sets the allowable upstream supply range. The through-hole TO-220F package supports through-hole board mounting and mechanical attachment. The specified temperature range is -40°C to 85°C. Protection features are limited to over temperature and short circuit. The part is listed as Active, and the 6 mA quiescent current and 78dB PSRR at 120Hz should be considered in power budget and ripple-sensitive designs.
