The regulator boasts a high-efficiency design, with a wide operating temperature range from -40°C to +105°C, as well as low supply current, low noise, and low power dissipation.

The basic circuit of the S-13R1G25-A4T2U3 consists of an integrated MOSFET, PNP transistor, current limit circuit, pull-up/down network, and error amplifier combined into a single chip. The MOSFET controls the output voltage, while the PNP transistor amplifies the error signals from the error amplifier to the gates of the MOSFET. The current limit circuit prevents excessive current from flowing through the power device, thereby protecting the device from damage. The pull-up/down network allows for variable output voltage, depending on the user’s requirements.

The S-13R1G25-A4T2U3 can be used in a variety of applications, including CPU core power supply, switching power supply monitor, display power source monitor, as well as post regulation in switch mode power supplies. It is especially suited for applications requiring high accuracy over temperature, tight regulation, and low power consumption.

The working principle of the S-13R1G25-A4T2U3 is relatively simple. It operates by functioning as an error amplifier that senses the output voltage and compares it to a reference voltage. When the output voltage is out of regulation with the reference, the error amplifier increases or decreases its output to the MOSFET gate, causing the MOSFET to adjust the power output and restore the voltage to the desired level.

The S-13R1G25-A4T2U3 features adjustable voltage ratings from 0.8V to 25V, providing for a wide range of voltages for a variety of applications. It has an input voltage range of 4.5V-25V and a max output current of 35mA. Furthermore, the voltage accuracy is as low as 0.5% over the -40°C to +105°C temperature range, making it an attractive choice for applications requiring high accuracy. In addition, the device features a shutdown input, enabling the user to turn off the regulator when not in use for power savings.

The S-13R1G25-A4T2U3 is an excellent choice for a wide variety of applications requiring high voltage accuracy, low power consumption, and low noise. Its adjustable voltage ratings, wide temperature range, and low voltage accuracy make it a great choice for applications requiring high accuracy over temperature. In addition, the device’s low power consumption, low noise, and shutdown input make it an attractive choice for applications where power savings are an issue.
