The S-1142D21H-E6T2U is a linear voltage regulator manufactured by Semco Instrument Co Ltd. It is a part of the company’s PMIC – Voltage Regulators – Linear product portfolio. It is specifically designed for power supply applications such as point-of-load converters, stop-start applications, and automotive systems.

The S-1142D21H-E6T2U has a wide input voltage range of 3.0 V to 36.0 V. It is a high-power linear regulator that can handle up to 6.0 A of load current. It features reverse-polarity protection, current-limiting, and thermal-shutdown protection. The regulator has a wide operating temperature range of -40 to +85 °C and is available in a standard 21-pin, hermetically sealed, ceramic package. It also has a high level of performance, since it provides a high accuracy of ±2.5%.

The S-1142D21H-E6T2U is suitable for applications such as distributed power supplies, telecommunications systems, industrial process controllers, DC-DC converters, motor drives, and general load-data distribution applications. It is used in automotive systems such as fuel injectors and power windows and in power supply systems for computers and other electronic devices. It is also used in aerospace and defense systems for power sources, analog-to-digital and digital-to-analog converters, and motor control systems.

The S-1142D21H-E6T2U works by regulating the output voltage to a precise level, regardless of changes in input voltage, temperature and load. It uses a series of transistors, resistors and capacitors to control the voltage. When the input voltage is higher than the output voltage, the regulator behaves like a current-limiting device, reducing the current flowing through the regulator. When the input voltage is lower than the output voltage, the regulator behaves like a voltage-limiting device, reducing the voltage across the regulator.

The S-1142D21H-E6T2 is also protected against reverse polarity and reverse current. This ensures that no damage occurs to the device if the input voltage is connected in reverse. Additionally, the device is protected from thermal-overload, which protects the regulator from damage in case of high output current. Additionally, the device provides overload protection, which shuts the regulator down in case of short-circuit or high-current.

Given its wide range of features, the S-1142D21H-E6T2U is a great choice for power supplies and voltage regulation. It is optimized for the needs of applications such as distributed power supplies and automotive systems, and can reliably protect sensitive devices from overcurrent and overvoltage. It offers high accuracy, wide temperature range and low power dissipation, making it a cost-effective choice for a variety of power requirements.
