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 SL4949 is a low-dropout (LDO) voltage regulator that outputs 5V. It integrates power-on reset functionality and input voltage monitoring internally. 

The SL4949 provides a stable power supply voltage for microcontroller control systems, with a typical output current of up to 100mA. It can handle transient input voltages up to 42V, making it highly suitable for automotive electronic environments.

It supports Reset output for microprocessor logic control and includes Sense monitoring, which can provide a warning signal before issuing the reset signal. Proper use of Sense monitoring allows the microprocessor to take necessary processing steps before Reset halts its operation.
