The S-1142B50H-E6T2U voltage regulator, which belongs to PMIC—Voltage Regulators—Linear, is a kind of linear voltage regulator. When external voltage is applied to the input side and the output side connected to the load, this voltage regulator can suppress the excessively high voltage and provide stable and reliable voltage for the electrical appliances in order to protect them from damage. Also, it is an excellent choice for applications which require low dropout voltage, low quiescent current, and high ripple reject capability.

Designing with this voltage regulator allows the user the flexibility of routing input and output voltage traces separately while having the option to route them together on the same layer to save board space. This voltage regulator includes an enable pin, which brings the device into a low standby current state when brought low. And it features fast response, high accuracy, low temperature drifts, and excellent transient pulse characteristics. It is also AEC-Q100 qualified, providing excellent performance in harsh environments, allowing this device to be used in automotive, industrial, and consumer application.

S-1142B50H-E6T2U Application Field and Working Principle

Application Field

The S-1142B50H-E6T2U is widely used in automotive, industrial and consumer applications. It provides an adjustable output voltage range from 0.9V to 6.0V, making it suitable to power chips, sensors, and other electrical parts. It is a good choice for applications that require low dropout voltage, low quiescent current, and high ripple rejection.

Working Principle

The S-1142B50H-E6T2U works by integrating control circuitry, reference voltage circuitry, switches, pass transistors, LEDs and a feedback circuit. The switcher of this device has an input side, a PWM control pin and an output side. When the power is turned on, the LED illuminates, powering the internal regulator and low voltage DC is sent out of the PWM control pin. This DC will turn the switches on, allowing current to flow from the input side to the output side. The output voltage is then adjusted according to the reference voltage on the reference voltage pin. The feedback circuit in the device constantly monitors the output voltage and ensures that the output voltage remains stable, which prevents overvoltage or undervoltage.
