The S-1142C35H-E6T2U is an integrated voltage regulator, part of a larger family of linear regulators. It is a 3.2A low dropout (LDO) regulator featuring integrated Power Good, enable and thermal protection outputs. It is designed for applications requiring high current capability and low dropout voltage.

Application Field:

The S-1142C35H-E6T2U is suitable for a wide range of medium to high current applications, such as automotive, general purpose, industrial and audio. It can be used for applications where a precise regulated supply voltage is needed, including power supplies for microcontrollers, FPGAs and integrated circuits. It is also suitable for protecting switches and transistors from over-voltage and over-current damage. It can also be used as a reliable DC/DC converter to provide a stable voltage source and keep the load within a defined voltage level.

Working Principles:

The S-1142C35H-E6T2U is a linear voltage regulator and consists of a large voltage MOSFET and a main driver transistor. The MOSFET act as a high efficiency switch and perform the most of the linear voltage regulation. It is divided into two stages: the balancing stage and the electrolytic stage. The balancing stage includes the output capacitor, the indicator lamps, the damping resistors and the current limiting resistor. The electrolytic stage acts as a buffer. When the voltage of the output increases, the electrolytic stage will absorb the excess voltage and when the voltage falls, the electrolytic stage will release its stored energy to maintain the output voltage.

The current limiting resistor limits the current from the output of the S-1142C35H-E6T2U, which prevents the device from overloading. The main driver transistor is connected to the drain of the MOSFET and its voltage is determined by the current source. This transistor regulates the voltage output. The voltage output of the S-1142C35H-E6T2U is also regulated by its internal thermal protection circuit. This circuit enables the device to detect the temperature rising above the specified temperature to protect against failure.
