The S-13R1C12-A4T2U3 is a Linear Voltage Regulator designed for Power Management Application Integrated Circuits (PMICs). It is a single-output, negative output, low dropout voltage regulator that supplies up to 500 mA of output current.

The S-13R1C12-A4T2U3 device provides high accuracy output voltage regulation. The device is designed to operate over a wide input voltage range of 2.5 V to 18 V. Its output voltage is internally trimmed to 2.4 V, or a selected output voltage of 1.2 V to 3.3 V can be provided. Its current-limit and thermal shutdown protection help prevent catastrophic failure or damage to the IC from overcurrent or overtemperature fault conditions.

The S-13R1C12-A4T2U3 device is ideal for applications requiring high current and low dropout voltages, such as LED bias supplies, battery chargers, and other portable and handheld applications. The device also features low quiescent current to support low-power operation. The device\'s output voltage is immune to line transients and output/ground terminal reverse leakage is less than 1.0 µA.

The operating principle of the S-13R1C12-A4T2U3 is based on the voltage divider principle, using two series-connected resistors. As the input voltage of the device increases, a proportional variation in the output voltage is obtained through the resistors\' voltage drops. This operation allows the device to regulate the output voltage without consuming additional current. When the load current is increased, the device is further efficient as it needs to recover only the voltage drop due to the load current.

The S-13R1C12-A4T2U3 device\'s ability to regulate the output voltage under a wide range of conditions makes it an ideal choice for a variety of power management applications. With its wide input voltage range, low quiescent current, and current-limit and thermal shutdown protection, it is suitable for a wide range of applications including battery-powered and portable systems, as well as applications requiring a high accuracy output voltage regulation.

The S-13R1C12-A4T2U3 device is capable of providing up to 500 mA of output current, making it an ideal choice for supplying power to a variety of high-current components in a variety of power management applications. Its low dropout voltage and high accuracy output voltage regulation make it suitable for a wide range of applications, such as LED bias supplies, battery chargers, and other portable and handheld applications.
