NJM431L

Overview

The NJM431L is a three-terminal adjustable precision shunt regulator manufactured by Nisshinbo Micro Devices Inc. utilizing bipolar technology. It features an operating voltage range from VREF (approximately 2.5V) to 36V, set via two external resistors. The device supports a cathode current range of 1mA to 100mA with a typical dynamic output impedance of 0.2Ω and load regulation of 0.1%. Absolute maximum ratings include a cathode voltage of 37V and continuous cathode current up to 150mA. It operates within a temperature range of -40°C to +85°C and is housed in a TO-92 package.

Feature Summary

Adjustable output voltage capability between approximately 2.5V and 36V using external resistors
Fast turn-on response characteristics for efficient switching applications
Low dynamic output impedance ensuring stable performance under varying loads

Applications

Shunt regulators
Series regulators for small power supplies
Isolation regulators with photocouplers
Constant current sources

Procurement Notes

Verify the specific ordering suffix and package type when sourcing, as the NJM431 series includes multiple variants such as DIP8, DMP8, SOT-89, and TO-92. Confirm RoHS compliance status and availability through authorized distributors, noting that certain packages may have different lead times or stock levels. Ensure the selected variant matches the required thermal dissipation and mounting style for the intended application design.

Selection Notes

Select the NJM431L specifically for designs requiring the TO-92 through-hole package format. Consider the 1mA to 100mA cathode current range and the 36V maximum operating voltage when designing the resistor divider network. Evaluate the thermal dissipation requirements against the 500mW rating specified for the TO-92 package at ambient temperatures up to 85°C to ensure reliable operation.

Part Context

The NJM431L belongs to the NJM431 family of adjustable precision shunt regulators produced by Nisshinbo Micro Devices Inc. This family utilizes bipolar technology and offers various package options including DIP8, DMP8, SOT-89, and TO-92. The components are designed for general-purpose voltage reference and regulation tasks in power management circuits.
