The S-812C31AY-Z2-U is a low-drop linear voltage regulator of high precision, low noise and low power consumption. It is part of a series of regulators from Diodes Inc. that offer a broad range of features and options for generating precision voltage levels. The S-812C31AY-Z2-U has an adjustable output voltage range from 1.6V to 6.5V, and a maximum output current rating of 3A. It is well-suited for powering low-current microprocessor cores, FPGAs, ASICs, digital logic, memory devices and ADCs.The S-812C31AY-Z2-U is designed to operate in a wide range of input voltages and provides excellent efficiency and thermal performance. The device features a low-noise, low-dropout linear regulator, adjustable through-hole pin, an enable control for ease of control and an internal thermal shutdown circuit to protect the device from excessive temperatures.The S-812C31AY-Z2-U operates on a “floating regulation” principle. This means that even when the output voltage changes, the input voltage to the regulator will remain constant regardless of the load current, which helps improve system reliability by avoiding possible power supply spikes. The output voltage of the regulator is adjustable with an onboard through-hole pin and a selected resistornetwork.The S-812C31AY-Z2-U supports a quiescent current of typically 20uA. This low power consumption allows designers to create ultra-low-power solutions and extend battery life in portable applications. The device is designed with the ability to run either in “sleep” or “run” mode. The regulator will automatically transition from sleep mode to run mode upon detecting a rising current load, allowing the regulator to adjust its output voltage to the load. This can be useful for conserving power in some applications where a variable load isn’t likely.The S-812C31AY-Z2-U has a wide operating temperature range from -20°C to 80°C and is housed in a TO-263 package. The package can be surface-mounted for easy installation and improved thermal performance, making it suitable for use in a variety of mobile, automotive, industrial and consumer electronics applications.The S-812C31AY-Z2-U is an excellent solution for applications requiring precision voltage levels and low power consumption. Its fast response and accurate tracking of the output voltage, along with its wide temperature range, make it an ideal choice for powering today’s wide variety of electronics and microcontrollers.
