NJR to Provide Samples of High Precision Adjustable Shunt Regulator NJM17431

New Japan Radio (NJR) launches a high precision adjustable shunt regulator NJM17431, and has begun providing sample products.

General Description

 NJR provids samples of a new adjustable shunt regulator NJM17431 with high precision and wide stable operation region*1 that has been designed by latest process and analog circuit technology for many years.
 Because the NJM17431 has 0.8% accurate voltage reference and wide stable operation region for large capacitive load, it can be used for a very wide range of applications. And it can replace Zener diode with the NJM17431.
 Since the stable operation region is wide, it will help engineers reduce the design man-hours and the burden of replacement evaluation.

*1 At it uses ceramic capacitor with capacitance value of around 1uF at the output of the general shunt regulator, will be enter in unstable region and operation is unstable.
 The NJM17431 operates stable in the range of 0.01μF to 100μF with the actual usage cathode current region.

Example of stable operation region



1. Reference Voltage Tolerance: 2.5V±0.8%
2. Adjustable Output Voltage:       VREF to 36 V
3. Wide Stable Operation Region
4. Low Temperature Coefficient of Voltage Reference
5. The output voltage can be set with two external resistors
6. Bipolar Technology
7. Package:          SOT-23-5


  • Industrial Equipment
  • HOME Appliances
  • Precision Power Supply
  • Zener Diode Replacement

Production Schedule

  • Enter mass-production in the second quarter of 2020
