The voltage reference operates as a low temperature coefficient zener which is programmable between VREF (2.5V) and 36 volts using two external resistors. The device has a wide operating current range of 1 m A to 100m A and a typical dynamic impedance of 0.2 Ω . Active output circuitry provides a very sharp turn-on characteristic making these...
