NJM431SF

NJM431S/NJM432S ADJUSTABLE PRECISION SHUNT REGULATOR ■ GENERAL DESCRIPTION The NJM431S/NJM432S are adjustable precision shunt regulators. The output voltage may be set to any value between VREF (about 2.5V) and 36V by two resistors. Compared to the conventional 431, the NJM431S/NJM432S are improved the voltage accuracy. And they have smaller package option to support a wide range of applications. The NJM432S is the pin assignment option. ■ PACKAGE OUTLINE NJM431SU NJM432SU (SOT-89-3) NJM431SF NJM432SF (SOT-23-5) ■ FEATURES ▪ Operating Voltage ▪ Precision Voltage Reference ▪ Adjustable Output Voltage ▪ Bipolar Technology ▪ Package Outline VREF to 36V 2.495±1.8% NJM431SU / NJM432SU NJM431SF / NJM432SF SOT-89-3 SOT-23-5 ■ BLOCK DIAGRAM / SYMBOL CATHODE CATHODE REFERENCE + VREF REFERENCE ■ PIN CONFIGURATION NJM431SU ANODE NJM431SF 5 4 ANODE NJM432SU NJM432SF 5 4 1 2 3 1.REFERENCE 2.ANODE 3.CATHODE Ver.2016-05-13 123 1.N.C. 2.ANODE* 3.CATHODE 4.REFERENCE 5.ANODE * Pin 2 is attached to Substrate and must beconnected to ANODE or left open. 1 2 3 1.CATHODE 2.ANODE 3.REFERENCE 123 1.N.C. 2.ANODE 3.N.C. 4.CATHODE 5.REFERENCE -1- NJM431S/NJM432S ■ ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL MAXIMUM RATINGS (Ta=25ºC) UNIT Cathode Voltage VKA Continuous Cathode Current IK Reference Input Current IREF Power Dissipation PD 37 (*1) V -100 to 150 mA -0.05 to 10 mA SOT-89-3 : 450(*2) : 1300(*3) SOT-23-5 : 480(*4) mW : 650(*5) Operatin...
