NJM7824FA

Product Overview

The NJM7824FA from Nisshinbo Micro Devices Inc. is a positive fixed-output linear voltage regulator intended for single 24 V DC regulation. The device is specified for up to 1.5 A output current and accepts input voltages up to 40 V. It is supplied in a through-hole TO-220F package, with a TO-220-3 Full Pack case designation. The regulator includes over-temperature and short-circuit protection and is rated for operation from -40°C to 85°C.

Key Features

• Fixed positive 24 V output in a single-regulator configuration.
• Rated output current of 1.5 A with maximum input voltage of 40 V.
• Quiescent current of 6 mA and power-supply ripple rejection of 66 dB at 120 Hz.
• Over-temperature and short-circuit protection features.
• Operating temperature range of -40°C to 85°C.
• Through-hole mounting in a TO-220F package (TO-220-3 Full Pack).

Applications

• Generating a fixed 24 V DC rail from a higher DC input in electronic assemblies.
• Post-regulating a 24 V supply for equipment circuitry that draws up to 1.5 A.
• Providing a through-hole 24 V regulator in board-level power distribution where a single fixed output is required.

Design & Procurement Notes

Design considerations include confirming that the input voltage does not exceed 40 V, the load current remains at or below 1.5 A, and the ambient operating range stays within -40°C to 85°C. Because the output is fixed at 24 V, external voltage adjustment is not available with this part. The through-hole TO-220F package affects board layout, mounting, and mechanical clearance. The over-temperature and short-circuit protection features should be considered within the overall power-supply fault strategy.
