SBOS283D September 2003 – March 2018 REF1112
PRODUCTION DATA.
The REF1112 device is effectively a precision Zener diode. The part requires a small quiescent current for regulation, and regulates the output voltage by shunting more or less current to ground, depending on input voltage and load. The only external component requirement are an resistor between the cathode and the input voltage to set the input current and an external capacitor at the output to maintain stability under varying loads.
