Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Description
● The SL2103 Series is a single-chip integrated low-dropout voltage regulator designed for  applications requiring ultra-low quiescent current, with a typical load current of 70mA.  This device comes in an SOT89-5L surface-mount package, suitable for supplying power  to MCU systems in harsh automotive environments, featuring additional protections for  overload, short circuit, and over temperature. Of course, the SL2103 can also be used in  any other application requiring stable voltage regulation.
● Within the range of 5.0V<VSP<42V, input voltage is regulated to an output voltage Vout with an accuracy of 1%.The SL2103-3.3 provides a 3.3V output, the SL2103-5.0  provides a 5V output, and the SL2103-ADJ offers an adjustable output voltage (refer to  specific formula 5.1).
