S-13R1H17-I4T1U3 is an integrated three-terminal linear regulator designed for applications requiring up to 1A output current. With high-performance input voltage noise level, it is well suited for supplying loads with low frequency. On-chip feedback and reverse-nucleation features ensure stability, making it suitable for battery applications.

In typical applications, this integrated voltage regulator can be used to drop the input voltage from 5V to 3.3V, regulating the output current up to 1A. It is also suitable for supplies of 3V to 12V and can be used as a low-dropout voltage regulator for applications such as battery-supplied digital systems and power supplies. The low noise and low quiescent current make it a good choice for low power applications.

In terms of performance, the S-13R1H17-I4T1U3 features an ult-low 47mV typical dropout voltage, a low 0.2% line regulation and a high 300mW operating power. It also features a low 200mV maximum reference voltage and a very low 0.3mA quiescent current. These features make the integrated voltage regulator suitable for use in very demanding power supplies as well as in low noise power applications.

In terms of its working principle, the S-13R1H17-I4T1U3 operates like any other linear voltage regulator. The input voltage is compared to an internally programmed reference voltage, and an error voltage is outputted in response. This error voltage then drives an internal pass transistor, allowing current to flow, thus regulating the output voltage. Current-limiting circuitry also controls the voltage drop across the pass transistor, as well as the overall current flow.

Finally, the S-13R1H17-I4T1U3 provides thermal and current overload protection features, making it suitable for use in demanding applications which require reliable operation. It also features a wide ambient temperature range and an adjustable output voltage, making it a great choice for adjustable and resettable 1A linear voltage regulators.
