Introduction

S-13A1B14-A6T1U3 is one type voltage regulator of linear PMIC (Power Management Integrated Circuits). This product adopt the 3-terminal regulator design and can provide maximum output current up to ±50mA. It provide adjustable output voltage from 9V to 90V, which suitable for middle and high voltage application.

Application Field and Working Principle

The S-13A1B14-A6T1U3 are mainly used in the display and lighting industry, instrumentation, computer peripherals, telecommunication products and industrial control system. It is widely used in portable medical equipment and communication products powered by single Li-ion battery. Besides, it can work as a voltage regulator in mode system to provide voltage for CPU and memories. As other linear voltage regulators, the S-13A1B14-A6T1U3 works by connecting an external resistor and capacitor in series between the output pin (Vout) and ground to set the output voltage required. The voltage regulator uses an error amplifier to compare the feedback voltage (Vout) to the reference voltage (Vref). The difference between these two values is used to adjust the current flowing through an external pass transistor. The control loop formed by the error amplifier and external pass transistor provides line and load regulation, even in the event of large output voltage fluctuations.The S-13A1B14-A6T1U3 is also featured with on/off feature and soft start function, which reduce output voltage overshoot during start-up. This product includes variable slew rate, maximum output current limit and thermal shutdown protects which make it suitable for high efficiency and high reliability system.
