The 2SC1093 are adjustable precision shunt regulators with guaranteed thermal stability.

A shunt regulator is an electronic circuit that regulates the voltage in a circuit by diverting excess current to a low-resistance parallel path when the voltage exceeds a specified limit. The purpose of a shunt regulator is to maintain a constant voltage level, regardless of changes in current demand, by bypassing excess current around a load and thereby preventing the voltage from dropping too low.

Shunt regulators are commonly used in power supplies and battery charging applications, where it’s important to maintain a constant voltage level to ensure stable operation of the load. They can also be used in applications where a high level of voltage regulation is required, such as in instrumentation and medical devices.

The output voltage can be set to any value between reference voltage (2.495 V) and 36 V by two external resistors.

These ICs can apply to error amplifier of switching regulators.
