• Soft start - The SG723T features a soft start feature that reduces current surge at start-up for increased reliability.

Working Principle

SG723T is a linear voltage regulator that works by using an internal MOSFET to switch the output voltage. The MOSFET is powered by a precision internal voltage reference and compared to the external voltage reference (adjustable from 1.2V to 16V). The internal MOSFET will then switch on or off according to the voltage difference between the two references, allowing current to flow or not flow in the desired amount.The SG723T is designed to provide adjustable enhanced load regulation and line regulation in order to maintain the output voltage either high or low. It also features a built-in temperature protection circuit to prevent excessive temperature and overloading.

Conclusion

SG723T is a low quiescent current linear voltage regulator designed and manufactured by Texas Instruments. It is designed specifically for automotive, computer, industrial, multimedia, mobile and telecom applications. The features of SG723T such as its wide input voltage range, adjustable output voltage range, low quiescent current, low ripple and noise reduction and its high efficiency make it an ideal solution for many applications. It also has a built-in temperature protection circuit which provides additional reliability and safety. The working principle of SG723T is based on the comparison of two voltage references, the internal and external voltage references. The internal MOSFET then switches on and off to regulate the output voltage, providing for adjustable enhanced load regulation and line regulation.
