NJM78M12FA 詳細描述
Product Overview
The NJM78M12FA from Nisshinbo Micro Devices Inc. is a positive fixed linear voltage regulator that delivers a single 12 V output at up to 500 mA. It accepts input voltages up to 35 V and uses a through hole TO-220-3 Full Pack package, also identified as TO-220F. The device has 6 mA quiescent current and 70 dB power supply ripple rejection at 120 Hz, with over temperature and short circuit protection. Its rated operating temperature range is -40°C to 85°C, making it suitable for board-level 12 V regulation in general electronic assemblies.
Key Features
- Fixed positive 12 V output with a single regulator.
- Output current rating of 500 mA and maximum input voltage of 35 V.
- Quiescent current of 6 mA.
- Power supply ripple rejection of 70 dB at 120 Hz.
- Over temperature and short circuit protection.
- Through hole TO-220-3 Full Pack package, TO-220F device package.
- Operating temperature range of -40°C to 85°C.
Applications
- Fixed 12 V rail generation for control, instrumentation, or general-purpose electronic boards.
- Post-regulation stage in linear power supplies accepting input voltages up to 35 V.
- 500 mA 12 V supply for low-power peripheral circuits and module-level regulation.
- Through-hole 12 V regulator for prototyping and maintenance of existing electronic assemblies.
Design & Procurement Notes
Design considerations should focus on the fixed 12 V output, 500 mA output current rating, and 35 V maximum input voltage. Because this is a linear regulator, the difference between input and output voltage will appear as heat, so layout, copper area, and ambient conditions should be evaluated for the expected load and operating temperature. The 6 mA quiescent current and 70 dB ripple rejection at 120 Hz are useful when selecting input and output filtering. The through-hole TO-220-3 Full Pack package requires appropriate board holes and mechanical clearance, while the rated -40°C to 85°C range defines the thermal operating window. Over temperature and short circuit protection should still be coordinated with system-level current limiting and thermal management.
