Reference Voltage Generator using LM139 Comparators Circuit and Datasheet - The schematic diagram illustrates how to generate voltage reference which will be used in such comparator applications using LM139 – monolithic quad of independently functioning comparators.

The circuit uses four independently variable voltages for low current supplies purpose in powering additional tools for generating reference voltage.

According to the LM139/LM239/LM339A datasheet, the use of suited Zener diode will provide all four voltage to be a near zero temperature coefficient.

As also said in the LM139 datasheet, the outputs of any of the reference supplies can be current boosted by using an external NPN transistor as an improved operational amplifier (fine also the circuit diagram of the op amp in the datasheet).
