The TA78L12F (TE12L,F) regulator can also be used for power supply voltage monitoring, over-voltage protection, or for controlling the output of a switching or linear power supply. With its low quiescent current, the TA78L12F can be used in applications that require low power consumption.

Working Principle

The TA78L12F (TE12L,F) is a voltage regulator that uses linear regulation technology to control the output voltage. The regulator consists of an input terminal, an output terminal and an adjustment terminal, which are used to configure the output voltage according to the required level. The input terminal is connected to the power source, while the output terminal supplies the regulated voltage to the load. The adjustment terminal is connected to the difference between the reference voltage and the output voltage.

The TA78L12F (TE12L,F) works by comparing the voltage present at the output terminal with the reference voltage. When the output voltage deviates from the reference voltage, the regulator adjusts the control element such that the output voltage matches the reference voltage. The control element can be a transistor, a MOSFET or a voltage control element.

The TA78L12F (TE12L,F) regulator also uses an error amplifier to compare the output voltage with the reference voltage. The error amplifier version is used to detect even small changes in the output voltage. When an error is detected, the error amplifier adjusts the control element to keep the output voltage at the reference voltage level.

The TA78L12F (TE12L,F) linear voltage regulator can provide a very stable output voltage, with a very high efficiency. Its wide input voltage range and low dropout voltage also make it suitable for most applications. Furthermore, the TA78L12F is designed to operate over a wide temperature range, making it highly suitable for industrial applications.
