Working Principle

The TC1107-3.3VOTR is a linear regulator that uses a linear control topology. The regulator uses two external resistors, R1 and R2, to convert the incoming unregulated voltage to a regulated 3.3V. The two resistors work together to form a Voltage Divider Network, where the Divider produces an output voltage that is related to the input voltage and the network\'s resistance. The regulator then amplifies this voltage using an internal amplifier and provides a stable 3.3V output.

The TC1107-3.3VOTR\'s internal amplifier is configured as a voltage regulator. When the input voltage is fluctuating, it regulates the output voltage to 3.3V. The regulator employs fold back current limitation and is protected against over temperature and short circuit. The TC1107-3.3VOTR is also immune to output capacitive transients.
