The S-817B40AY-B2-U is an adjustable low dropout (LDO) linear voltage regulator that is part of the PMIC – Voltage Regulators – Linear category. It is an easy-to-use regulator that is designed to provide a regulated output voltage from any input voltage higher than the regulator’s minimum input voltage, down to a minimum of 1.25V.

The S-817B40AY-B2-U is designed for analog and digital circuits that require a high accuracy, low dropout and low quiescent current. It is also designed for output voltage accuracy up to 1% and low temperature drift. Starting from an input voltage of 2.5V, the S-817B40AY-B2-U can provide an output voltage range from 1.25V to 44V, with an adjustable output voltage setting of up to two decimal places in between.

It has a wide operating temperature range of -40°C to +125°C, making it suitable for a variety of different applications and conditions. The S-817B40AY-B2-U also features short-circuit protection and over-current protection, allowing it to protect itself and the circuit against serious damage or failure.

The S-817B40AY-B2-U also features a low quiescent current, meaning that power consumption and heat dissipation are minimal. It has an adjustable output current of up to 1A, and is provided in a low profile SOP 8-pin package. This makes the S-817B40AY-B2-U suitable for many convenient and demanding applications.

The S-817B40AY-B2-U is ideal for a wide range of applications that require low noise, low dropout, high accuracy and a fast response linear voltage regulator. This can include, for example, portable communication devices, automotive electronics, DSP/MCU circuits and LCD panels.

The S-817B40AY-B2-U works by taking an input voltage and regulating this voltage to a specified value, with the value of the output voltage varying depending on the load. The regulator uses an internal sensing circuit and a series of transistors to compare the output voltage and the reference voltage, and control the output voltage. The reference voltage is determined by a voltage divider, which uses two external resistors to set the voltage. The output voltage is then adjusted accordingly.

The S-817B40AY-B2-U is a simple, efficient and reliable solution for those applications that require an adjustable low dropout linear voltage regulator.
