It has a low quiescent current and low noise operation, making it ideal for low-power applications or for applications that need extremely low power consumption.

The S-1131B38UA-N4XTFG is a three-terminal, fixed-output, adjustable-current linear voltage regulator. The device is available in two versions: P (positive output) and N (negative output). It features a low dropout voltage (typicall 2V), a high output voltage accuracy (±3.3%, typ) and a low-temperature coefficient (±5mV/°C). It can drive with a 10mA current and can provide a maximum output current of 1.2A.

The working principle of the S-1131B38UA-N4XTFG linear voltage regulator is based on a voltage divider circuit, with a series of resistors connected between the input voltage and the output voltage. The feedback loop maintains the output voltage at a constant level, regardless of the fluctuations in the input voltage. The dropout voltage of the regulator is the difference between the input and output voltages when the output voltage starts to drop below its desired level.

The S-1131B38UA-N4XTFG delivers constant regulated voltage with excellent line and load regulation. It uses a common-mode rejection circuit (CMR) to regulate the output voltage from wide ripple noise and other disturbances. The regulators also employ an error amplifier to detect and adjust the output voltage according to the input voltage.

The S-1131B38UA-N4XTFG is a widely used and versatile device that has applications in many different areas such as consumer electronics, automotive, audio, and industrial control. It is designed to provide accurate voltage regulation and stability when used in conjunction with other power supply solutions, such as DC-to-DC converters and switching power supplies. The device is also used to provide over-current protection, voltage cutoff, and voltage limiting. The S-1131B38UA-N4XTFG linear voltage regulator is an ideal choice for many types of power supplies due to its wide input/output voltage range, low dropout voltage, and high output voltage accuracy.
