The S-817A23APF-CUMTFU voltage regulator is a linear regulator from the PMIC - Voltage Regulators - Linear product family. It is designed to provide optimal power management solutions for multiple applications, including industrial and consumer devices, telecom and data center systems, automotive and automotive aftermarket systems, and more.

This voltage regulator is a highly integrated, single-channel device that provides a regulated output voltage with a wide operating temperature range, high precision, and low power consumption. It features integrated low-dropout (LDO) linear regulators, over-voltage protection (OVP) circuitry, over-temperature protection (OTP) circuitry, and current-limit protection (CLP) circuitry. It also supports fast transient responses, as well as designed current-mode/pulse-width modulation (PWM) control.

The S-817A23APF-CUMTFU voltage regulator offers an input voltage range of 4.5V to 27V and an output voltage range of 0.8V to 5.5V. It is recommended for applications requiring low noise, low power consumption, and high precision output voltage regulation. It also provides excellent line and load transient performance, making it suitable for applications where output voltage accuracy is critical.

The working principle of the S-817A23APF-CUMTFU voltage regulator utilizes a linear regulator approach. It uses an error amplifier to sense the output voltage and compare it with a reference voltage. If the output voltage exceeds the reference voltage, then the error amplifier will reduce the current to the pass transistor. This reduces the voltage drop across the pass transistor and therefore reduces the output voltage until it is equal to the reference voltage.

The S-817A23APF-CUMTFU voltage regulator also has an internal and external compensation pin, which provides additional control over the output voltage level. By adjusting the external compensation pin, the device can be configured for a wide range of output voltage values. The S-817A23APF-CUMTFU voltage regulator also has a user-configurable current-limit function, which allows the user to set the maximum current output of the device.

In addition, the S-817A23APF-CUMTFU voltage regulator is designed with built-in thermal protection, typically limiting the output current to a safe range in order to prevent damage to the device due to overheating. It also features a power-saving shutdown mode that reduces the power consumption in standby mode, helping to maximize battery life.

The S-817A23APF-CUMTFU voltage regulator is an excellent choice for applications requiring high precision voltage regulation. It provides reliable performance with user-configurable over-voltage protection, over-temperature protection, and current-limit protection. Its wide input voltage range and low power consumption make it an ideal solution for many different applications.
