The S-13R1H22-I4T1U3 is a type of linear voltage regulator integrated circuit (IC) from the S-13 family of voltage regulators. This type of circuit is long used for PMIC (power management) applications and is also commonly used for applications as a 3.3V or 5V logic interface or power supply.

The S-13R1H22-I4T1U3 is an ideal solution when an adjustable Voltage regulator is needed. It allows the user to have flexibility in setting the output voltage and current limits over wide range of input voltage. The output voltage can be set by connecting an external resistor divider to the ADJ pin of the device. This device has an internal thermal overload protection, overtemperature protection and short circuit protection. A dedicated power-on reset circuit also provides a reliable startup behavior.

In terms of the working principle of S-13R1H22-I4T1U3, it follows a conventional linear regulator circuit, meaning that the output voltage is derived from the input voltage via a series of linear components. This includes a feedback network and a unit referred to as an error amplifier. The feedback network adjusts a reference voltage at the positive input of the error amplifier by using a voltage divider consisting of external resistors. The error amplifier compares the reference voltage with its negative input, which is connected to the circuit output voltage. The resulting difference in voltage is then amplified and the output of the error amplifier is used to control the transistor, which acts as an active resistor in series with the output voltage. This active resistor continually adjusts to ensure that the output voltage is regulated.
