During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative applications. These include voltage comparators, ...

Still, the voltage ... MPPT and switch-mode circuitry might not seem justified, making linear regulation the simpler and better choice. This Design Idea addresses such systems, focusing on the ...

The circuit has a shunt regulator, internal voltage and bias current generators, built-in power-on-reset and oscillator. The core is easily retargeted to any other CMOS technology with R-poly devices.
