Power management ICs (PMICs) have been around for a long time, and a wide variety of them have been developed to meet different needs. One of the most common PMICs is the linear voltage regulator, which is used to regulate the output voltage of a power supply. The S-1142BB5H-E6T2U is a linear voltage regulator from TDK Corporation\'s S-LDO (Low Drop-Out) series. This device is widely used in a variety of applications, and in this article, we will discuss its application field and working principle.

Overview of S-1142BB5H-E6T2U

The S-1142BB5H-E6T2U is a low-dropout (LDO) linear voltage regulator that provides a constant output voltage while regulating the input voltage within its specified limits. This device is capable of operating with an input voltage of up to 11 V and an output voltage of as low as 1.7 V. It provides a maximum output current of 420 mA, and a maximum power dissipation of 750 mW. It has an excellent line and load regulation, with a minimum dropout voltage of 250 mV and a fast-response time of 8 µs. The device also features an adjustable output voltage, which is controlled by an external resistor. In addition, the device has a temperature range of -40 °C to 85 °C and a PSRR of up to 64 dB at 1 kHz.

Application Field of S-1142BB5H-E6T2U

The S-1142BB5H-E6T2U is widely used in a variety of applications due to its combination of high performance and low power consumption. It is suitable for a wide range of power supply designs, including portable devices, modems, scanners, and other digital circuits. In addition, it is a good choice for battery-powered devices, as its low dropout voltage means that it can be used with a variety of battery types. Finally, the device is often used as a stabilizer in power supply systems in industrial, automotive, and medical applications, as it is designed to regulate the input voltage and provide a stable output voltage.

Working Principle of S-1142BB5H-E6T2U

The S-1142BB5H-E6T2U is a linear voltage regulator, meaning it operates using the principle of linear regulation. This means that the output voltage of the device is directly proportional to the input voltage. The device is composed of two main components – a reference voltage (Vref) and a series transistor (MOSFET). The reference voltage is used to control the base voltage of the MOSFET, which acts as a variable resistor. Thus, when the input voltage increases, the MOSFET will reduce its resistance, and the output voltage will increase accordingly. Similarly, when the input voltage decreases, the MOSFET will increase its resistance, and the output voltage will decrease accordingly.

In addition, the S-1142BB5H-E6T2U has a temperature protection feature which will automatically shut down the device in the event of an overtemperature situation. This helps prevent damage to the device by preventing excessive current flow. The device also has a fast-response time of 8 µs, which makes it ideal for applications that require quick response times, such as in medical and automotive applications.

Conclusion

In conclusion, the S-1142BB5H-E6T2U is a high-performance linear voltage regulator from TDK Corporation\'s S-LDO series. It is well suited for battery-powered devices, portable devices, modems, scanners, and other digital circuits. It operates using the principle of linear regulation, and has a minimum dropout voltage of 250 mV and a temperature range of -40 °C to 85 °C. Additionally, the device has a fast-response time of 8 µs and a temperature protection feature which helps protect against damage caused by excessive current flow. This device is a great choice for projects requiring reliable and efficient voltage regulation.
