NJM431D

Overview

The NJM431D is an adjustable precision shunt regulator in a DIP-8 package. It operates with a cathode voltage range from VREF to 36V and supports a continuous cathode current of 1mA to 100mA. The reference voltage is typically 2.495V, with a maximum tolerance of ±2.2%. Key electrical characteristics include a dynamic impedance of 0.2Ω typical and a load regulation of 0.1% typical. The device functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Adjustable output voltage set between approximately 2.5V and 36V using two external resistors
Fast turn-on response with sharp switching characteristics
Low dynamic output impedance for stable regulation performance

Applications

Shunt regulators
Series regulators for small power applications
Isolation regulators with photo couplers
Constant current sources

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before implementation. Confirm availability through authorized distributors as stock may be limited. Ensure the DIP-8 package matches the target PCB footprint. Review the datasheet for absolute maximum ratings to prevent damage during operation.

Selection Notes

Select this component for applications requiring a low-cost, bipolar technology shunt regulator. Consider the 8-DIP package for through-hole mounting requirements. Evaluate the thermal dissipation limits relative to ambient temperature conditions. Compare against surface-mount alternatives if board space is constrained.

Part Context

This part belongs to the NJM431 series of adjustable precision shunt regulators manufactured by Nisshinbo Micro Devices. The series includes variants such as NJM431U and NJM431M in different packages. The NJM431D specifically utilizes a DIP-8 outline, distinguishing it from the SOT-89 and DMP8 options available in the family.
