Application Field and Working Principle of S-13AE15-U5T1U3 Linear Voltage RegulatorLinear voltage regulators are commonly used as adjustable power supplies in a variety of applications. The S-13AE15-U5T1U3 is a low-dropout (LDO) linear voltage regulator designed to provide adjustable output voltage in a wide range of applications such as computer motherboards, battery-operated devices, automotive systems, and audio/video equipment.An LDO is a type of linear voltage regulator that does not require the input voltage to be considerably higher than the output voltage, eliminates the need for bulky external components and reduces power consumption. This makes the S-13AE15-U5T1U3 an ideal choice for cost-sensitive projects that require minimal component count and board space.The S-13AE15-U5T1U3 is a three-terminal, regression voltage regulator that operates from an input voltage of 3 V to 15 V and provides an adjustable output voltage with a range of 0.8 V to 4.2 V. It is manufactured using a CMOS process and can deliver up to 100mA of output current. Its low-dropout voltage is no more than 350mV, making it suitable for portable applications.The S-13AE15-U5T1U3 is designed with current limiting and thermal shut-down features to protect the device, as well as external components, from possible damages. When the input voltage is rising above the output voltage, the current limiting protection will change the output voltage to prevent excessive current in the device. And, when the junction temperature of the S-13AE15-U5T1U3 reaches approximately 150°C, the thermal shut-down protection will lower the output voltage to 0V.The S-13AE15-U5T1U3 can be easily integrated into the system by simply connecting an external resistor between the output pin, OUT, and the adjust pin, ADJ. The OUT voltage = (1+ R2/R1)*VREF, where VREF is the reference voltage of 0.8 V. The resistor ratio will then determine the output voltage of the S-13AE15-U5T1U3.In applications such as producing auxiliary supplies in laptop computers and powering audio/video equipment, the adjustable S-13AE15-U5T1U3 linear voltage regulator provides a precise and low cost solution for voltage regulation. In addition, due to its low-dropout voltage (max. 350 mV), the S-13AE15-U5T1U3 prolongs battery life in portable applications. The S-13AE15-U5T1U3 also includes current limiting and thermal shut down protection to ensure safe operation. With its adjustable output voltage, this LDO linear voltage regulator is an excellent choice for many different applications.
