Working Principles

The TC1303C-ZA0EUNTR is a voltage regulator that takes an input voltage within the range of 2.5V to 6.0V and provides a regulated output voltage within the range of 1.2V to 5.5V. It achieves this by using an internal control circuit that adjusts the duty cycle of an internal switch, thereby regulating the output voltage.

The regulator operates in a pulse-width modulation (PWM) mode, where the duty cycle is adjusted based on the feedback received from the FB pin. This feedback signal is compared to a reference voltage internally, and the control circuit adjusts the duty cycle accordingly to maintain a stable output voltage.
