Overview
SC431M Adjustable Shunt Regulator Features  Wide operating current range 130μA to 150mA  Low dynamic output impedance 0.
25Ω typ.
 Trimmed bandgap + 0.
5%  Alternate for TL1431, TL431, LM431& AS431  Military temperature range  Available in SOT-23-3 package, fully WEEE and RoHS compliant Applications  Linear Regulators  Switching Power Supplies Typical Application Circuit Description The SC431M is a three terminal adjustable shunt regulator with thermal stability guaranteed over temperature.
The output voltage can be adjusted to any value from 2.
5V (VREF) to 30V with two external resistors.
The SC431M has a typical dynamic output impedance of 0.
25Ω.
Active output circuitry provides a very sharp turn on characteristic, making the SC431M an excellent replacement for Zener diodes.
The SC431M shunt regulator is available with a 0.
5% voltage tolerance over TA = -55°C to +125°C and comes in a SOT-23-3 package.
Notes: 1) Set VOUT according to the following equation...
