The S-13R1H29-N4T1U3 is a highly efficient, monolithic low-dropout regulator with two integrated and adjustable voltage oscillators - a precision bandgap reference, and an adjustable and buffered charge pumps - that are integrated into the IC. This linear voltage regulator provides superior regulation accuracy, low quiescent currents, and wide input and output voltage ranges. The S-13R1H29-N4T1U3 is an ideal solution for low power applications in data converters, audio systems, and communication and telecommunication equipment.

Application Fields

The S-13R1H29-N4T1U3 is designed for use in a variety of linear applications that require very low quiescent current, such as low-power low-dropout (LDO) regulators in data converters, audio systems, and communication and telecommunication equipment. It can also be used as a medium output current (up to 750mA) regulator for general-purpose power supply applications. Additionally, the S-13R1H29-N4T1U3 is suitable for use in precision applications where an accurate, stable output voltage is required, such as in high-end audio systems and low-power battery-powered circuits.

Working Principle

The S-13R1H29-N4T1U3 is a two-supply adjustable voltage regulator with two integrated and adjustable voltage oscillators. The precision bandgap reference and the adjustable and buffered charge pump are used to maintain a highly accurate output voltage level. The regulated output voltage of the S-13R1H29-N4T1U3 can be adjusted over a wide range of outputs, depending on the voltage of the Vref and the internal charge pump. Additionally, the output accuracy of the S-13R1H29-N4T1U3 can be improved by using an external precision reference. The current limit is adjustable through an external resistor to set the desired output current.

The S-13R1H29-N4T1U3 operates from two inputs - a regulated voltage input, V_IN and a Vref input. The input voltage, V_IN, is used to supply the power to the IC and should be kept as close as possible to the output voltage. The Vref input supplies the voltage reference for the output voltage regulation. The output voltage is set by an external resistor divider or an optional precision resistor divider. The load current is controlled by the voltage signal applied to the internal current limit terminals.

The S-13R1H29-N4T1U3 is designed to have very low dropout voltage and very low quiescent current. The IC has an operating temperature range of -40°C to+85°C and is protected from over-current and over-voltage situations. It is available in a 16-pin DIP or 14-pin SOIC package.
