Working Principle

The LT1963EFE#TRPBF is a voltage regulator that follows the control-loop architecture, with the following components: voltage reference, error amplifier, pass-transistor, and external resistor divider. The device works in the following manner:

• The voltage reference module provides the reference voltage, which is compared with the output voltage through an error-amplifier. If the output voltage is not equal to the reference voltage, an error signal is generated.
• This error signal is then used to control the gate voltage of the pass-transistor. This transistor acts as a switch and allows the input voltage through the circuit.
• The voltage then passes through a resistor divider, which sets the output voltage.
• The device also has protection features, such as thermal and reverse current protection, which ensures the device’s safe operation. The device also has an adjustable current limit feature, for current-limited applications, such as charging applications.
