Introduction

The S-13R1A35-A4T2U3 is a low-dropout (LDO) linear voltage regulator developed by Seiko Epson Corporation. It is a general-purpose physics-based regulator, providing a high precision voltage regulator solution for a variety of designs. It can be used in applications that require an input voltage range of 3.3 to 5.5V, and has a maximum output current of 35A. The output voltage is adjustable and can be set between 2.5V and 5.5V. In addition, the S-13R1A35-A4T2U3 is designed to be stable with all types of capacitive heating, and the voltage regulator can operate at temperatures up to 125°C.

Application Field

The S-13R1A35-A4T2U3 is suitable for a variety of applications, including automotive and industrial applications requiring tight voltage regulation or very low voltage dropout (LOD). The regulator has a high output power capability and can handle 35A at 2.5V, allowing it to power multiple integrated circuits which require a high current. In addition, its high power density allows it to be used in lightweight, low-power systems.Other applications for the S-13R1A35-A4T2U3 include providing a stable power supply for automotive drive, communication and computer circuits; powering small displays; providing stable power for RF and integrated circuits; and supplying highly accurate voltage for precision instruments.

Working Principle

The S-13R1A35-A4T2U3 operates on a simple, physics-based principle. In brief, it uses an NPN bipolar Junction Transistor (BJT) to generate a stable output voltage, regardless of changes in load current or input voltage. The BJT is connected to an adjustable voltage reference, which is controlled by two resistors (R1 and R2).The input voltage is applied to the base of the BJT and current flows through R1 in proportion to the voltage drop across its terminals. The voltage drop across R2 is proportional to the output current, thus providing the required feedback control of the output voltage. When adjustments are necessary, the two resistors are adjusted to change the voltage reference, allowing the output voltage to be precisely adjusted.

Conclusion

The S-13R1A35-A4T2U3 is a highly precise, low-dropout linear voltage regulator designed for a wide range of applications. Its high output power capability makes it an ideal choice for powering multiple integrated circuits, powering low-power systems, providing stable power for automotive circuits, and supplying accurate voltage for precision instruments. It is based on a simple physics-based principle, using an NPN bipolar Junction Transistor and an adjustable voltage reference to generate a stable output voltage.
