Switching regulators, also called switched-mode power supplies (SMPS), are dynamic power supply circuits that continuously regulate their output while providing a high-efficiency operation. However, when operating conditions require a precise output voltage or current level, or if the load or power-supply impedance changes, then a linear voltage regulator would be the right choice. Such is the case with the S-1142D34H-E6T2U.

This linear voltage regulator is designed for medium-power applications that require precise, precision regulation. It is optimized for systems that require low noise, low quiescent current, and low power consumption from 3.3 to 5V. Some typical applications for the S-1142D34H-E6T2U include industrial controllers, point-of-sale terminals, LED lighting systems, data communication systems, power-bank chargers, wireless and portable devices, solar inverters, and traction equipment.

The S-1142D34H-E6T2U is a low-dropout (LDO) regulator, which means it is capable of providing a stable output power level even when the input voltage is close to the output voltage. It features low dropout voltage (typically 600mV at full load and 8V as the maximum input voltage) and can achieve a load regulation of 0.5%. It offers a wide current range of 1mA to 4A and a thermal shut-down protection of 160°C.

The S-1142D34H-E6T2U is a current-regulated device. It works by comparing the actual output current with the current that is delivered to the load. When the output current is lower than the load current, the device reduces its internal resistance, thus allowing more current to flow through the device. This mechanism is designed to ensure that the output voltage will remain constant with changes in the load current.

The S-1142D34H-E6T2U also features a low-power mode and a sleep mode. The low-power mode reduces the quiescent current from 4.2mA to 1mA, while the sleep mode reduces it to 0.1mA. These features enable the device to reduce its power consumption while in standby, thus increasing power efficiency.

The S-1142D34H-E6T2U also features a soft start function that reduces output voltage overshoot during power-on and reset, and a reverse current protection that prevents current backflow in case of a shut-down. In addition, it has an undershoot protection and an overvoltage protection to prevent output voltage undershoots and to protect the device from excessive voltage.

This linear voltage regulator is packaged in a 6-pin SOT-223 package and can operate at temperatures from -40°C to 125°C. It has an internal power-on reset function that ensures that the device will remain in a safe environment upon power-up and power-down.

In short, the S-1142D34H-E6T2U is an ideal choice for medium-power applications that require precise, precision regulation. Its low-dropout and low-power modes combined with its protection features make it well-suited for power-sensitive applications, such as wireless and portable devices, solar inverters, and traction equipment. This linear voltage regulator is sure to be a valuable addition to any design.
