STMicroelectronics Voltage Regulators - Linear ST2L05R3318PT

The ST2L05R3318PT is a dual linear voltage regulator from Quarktwin Technology Ltd. designed to provide two outputs, each capable of delivering up to 1A of current. It features fixed output voltages of 3.3V for the first regulator and 1.8V for the second, which can also be adjusted from 1.25V to the input voltage minus the dropout voltage. The device has an output tolerance of ¬±2% at 25¬8C and ¬±3% over the specified temperature range, ensuring stable performance. With a typical dropout voltage of 1.1V at full load, the regulator operates efficiently with a very low quiescent current of 7mA maximum. It is designed for a wide operating temperature range of 0¬8C to 125¬8C and includes internal power and thermal limiting features for enhanced reliability. The ST2L05R3318PT is available in multiple package options, including PPAK, SPAK, and a compact DFN 5x6mm package, making it suitable for various applications, particularly in data storage devices such as hard disks and optical drives.
