STMicroelectronics Voltage Regulators - Linear ST2L05-3300K5

The ST2L05-3300K5 is a dual voltage regulator from Quarktwin Technology Ltd. designed to provide two outputs, each capable of delivering a guaranteed output current of 1A. It features fixed output voltages of 3.3V for the first regulator and an adjustable output for the second, ranging 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 entire temperature range, which spans from 0¬8C to 125¬8C. The typical dropout voltage is 1.1V when both outputs are operating at 1A. It is designed with internal power and thermal limiting features, ensuring safe operation under various conditions. The ST2L05-3300K5 is stable with low ESR output capacitors and has a low quiescent current of 7mA maximum. It is available in multiple package types, including PPAK, SPAK, and a compact DFN 5x6mm package, making it suitable for space-constrained applications. This regulator is particularly well-suited for data storage applications, such as hard disks and optical drives.
