onsemi Programmable Shunt Voltage Reference 2.5 - 36V ±1.0 % 3-Pin TO-92, KA431AZBU

For low power, low current applications, the shunt regulators from Fairchild Semiconductor feature adjustable/programmable output voltages with superb thermal stability. The shunt regulators provide low dynamic output impedance and fast turn-on response while operating over the industrial temperature range.
