applicaTions inForMaTion
The reverse characteristics of the LT1634 behave like VIN ≥ 10.5V a resistor in paral el with a Zener diode. This simple, RB = VOUT – 1.25V well behaved characteristic is important to the proper 10µA + operation of circuits like Figure 1. The adjustable output V LT1634-1.25 LT1495 OUT 1.5V TO 10V voltage reference depends upon positive feedback from – R1 50k TO 1.75M the LT1495’s output to start-up and regulate the bias cur- rent for the LT1634.
