S-13R1H35-A4T2U3

The S-13R1H35-A4T2U3 is a linear voltage regulator that belongs to a category of power management IC (PMIC) devices, called voltage regulators. Regulators are used to convert one voltage to another or to maintain the output voltage at a predefined level in spite of wide input dc voltage range and load variations.

This voltage regulator is specially engineered to provide uninterrupted support when exposed to irregular transient signals and to successfully handle the wide input voltage range of 4.0V to 18.0V.Moreover, It offers a fast trade-off between acceleration, recovery and transient response and consists of a band gap circuit and a transconductance amplifier connected in series. The integrated bandgap reference adds precision to the regulation loop, whereas the transconductance amplifier works in current mirroring mode to feed the output voltage to the ground. The transconductance amplifier can be considered as a self-regulating control device which maintains the output signal in a predefined level under changing applied load conditions.

The S-13R1H35-A4T2U3 is a particularly rugged regulator with low power dissipation, ideal for automotive and industrial applications. It comes with a wide operating temperature range and can sustain extreme ambient temperatures without sacrificing performance. It features a cycle-by-cycle current limit protection, providing reliable protection to the load against excessive power dissipation.

Additionally, the device has considerable margins in terms of frequency of operation, depending on the current levels. By adjusting the voltage across the regulator, it is possible to control the output current and voltage. This voltage regulator comes with a wide range of features and protection circuits, such as Overvoltage, Undervoltage and Reverse Polarity protection, Unique Thermal Management System and Flexible current-limiting parameters.

The S-13R1H35-A4T2U3 can be used for a variety of applications, including battery and load management, high load tests, emergency power supply systems and automotive, telecommunications, industrial and military applications. Due to its robust design, it is also suitable for harsh environment operations, like those encountered in aircrafts and motor vehicles.

The S-13R1H35-A4T2U3 includes a power supply controller, a timer oscillator, a current source and a voltage sensing circuit. The oscillator is used to generate a controlling clock signal, which regulates the power supply. The current source is used to maintain a uniform output current, and the voltage sensing circuit senses changes in the output voltage and ensures that the output voltage is always within the required range.

The S-13R1H35-A4T2U3 is an excellent choice for a wide range of applications. It offers reliable performance under varying input voltages and load conditions. Furthermore, it offers protection against overvoltage, undervoltage and reversed polarity, plus a thermal management system. As such, the S-13R1H35-A4T2U3 is an ideal choice for many applications requiring a stable voltage and current supply.
