ELM0431BA

ELM0431BA 2.5V Programable shunt regulator ■General description ELM0431BA is three-terminal adjustable shunt regulator utilizing an accurate 2.5V band-gap reference. The output voltage can be set to any value between 2.5V (Vref) to 29V with two external resistors as shown in the typical application circuit. The device exhibit a wide operating current range of 0.4 to 100 mA with a typical dynamic impedance of 0.25Ω. The characteristics of these reference make it excellent replacements for zener diodes in many applications such as digital voltmeters, power supplies, and op amp circuitry. The 2.5V volt reference makes it convenient to obtain a stable reference from 5.0V logic supplies. ELM0431BA shunt regulator is available in a SOT-23 package. ■Features Low cost solution Shunt capacity Output voltage range(adj.)
