The S-1131B26UC-N4LTFU is a linear voltage regulator from Renesas Electronics Corporation. This voltage regulator is specifically designed for applications where a low-noise, highly regulated power source is required. It has a wide input voltage range of 4.5V to 24V, and its output voltage is adjustable to meet various power requirements. The supply current is adjustable from 0.3mA up to 4A. The S-1131B26UC-N4LTFU linear voltage regulator uses a controlled series pass transistor, allowing for more precise control features than traditional linear regulator designs. It has low temperature drift of less than +/- 25ppm/°C and low output noise of less than 30mV RMS (with an input voltage of 12V).

The S-1131B26UC-N4LTFU voltage regulator is designed to provide a stable and consistent output voltage despite fluctuating input currents. It has a high input ripple rejection of 80dB at a frequency of 1,000Hz. The current limit and thermal protection provide added safety in the event of overloading or over-temperature. This voltage regulator is available in three package types: TO-220-4, TO-263-4L, and DPAK-4.

The basic operating principle of the S-1131B26UC-N4LTFU linear regulator is to use an op-amp to compare the output voltage to an internal reference voltage. The error signal is then amplified and the output from the amplifier is used to control an exhibition series pass transistor (emitter follower). When the output voltage deviates from its desired value, the op-amp will adjust the current through the dump transistor, thus adjusting the output voltage. The S-1131B26UC-N4LTFU also uses error-amplification and current-limiting circuits to ensure a stable output voltage.

The S-1131B26UC-N4LTFU voltage regulator can be used in a wide range of applications, including embedded systems, computer motherboards, industrial equipment, automotive systems, medical equipment and more. Its low noise and high accuracy make it suitable for providing a reliable power supply in these and other applications. Its high input ripple rejection makes it well suited for applications where high frequency interference is present. The dual-package and adjustable current capability make it a versatile voltage regulator solution.

In summary, the S-1131B26UC-N4LTFU is a highly efficient and reliable linear voltage regulator from Renesas Electronics Corporation. It has a wide input voltage range, and its output voltage is adjustable to meet various power requirements. It uses a controlled series pass transistor to provide precise control, and its low output noise and temperature drift make it suitable for many noise-sensitive applications. Its dual-package and adjustable current capability make it a versatile voltage regulator, and its high input ripple rejection make it a good choice for applications where high frequency interference is present.
