The working principle of the KA79M12TU Linear Regulator is based on the concept of adjusting the output voltage according to the change of the input voltage. At the same time, the built-in error amplifier in the chip compares the reference voltage and the feedback voltage and provides a signal for the control element. The control element, in accordance with the signal generated by the error amplifier, adjusts the on and off time of the internal switching tube. By controlling the ratio of the on-time and off-time, the output voltage can remain at a constant value. This allows the device to realize stable voltage output, high output accuracy and low dropout voltage.

When in operation, the KA79M12TU Linear Voltage Regulator works in a pulse width modulation (PWM) control mode. The built-in error amplifier compares the reference voltage and the output voltage to generate the signal, which is fed to the PWM comparator to detect the presence of output signal deviation. When the discrepancy is detected, the internal PWM signal will be turned off, resulting in a decreased output voltage. This signal will continue to be generated until the output voltage reaches the reference voltage.

The KA79M12TU Linear Voltage Regulator provides an adjustable voltage output from 1.0V to 6.0V, with high tolerance to output voltage ripple. The device offers a 200mA maximum output current and 2% output accuracy. Furthermore, the regulator provides excellent protection against short circuit and over-voltage protection.
