WebSep 15, 2015 · In a switching regulator the system variable is voltage (and/or current) which is compared with a reference value set by the circuit designer. The output from the error amplifier (the error signal) is then fed into a comparator that adjusts the duty cycle of the switching transistor. The duty cycle is proportional to the output voltage. WebIt acts as a buffer for protecting components from damages. A voltage regulator is a device with a simple feed-forward design and it uses negative feedback control loops. There are mainly two types of voltage regulators: Linear voltage regulators and switching voltage regulators; these are used in wider applications.
