ST2L05 is a low power dual voltage regulator from ST company. The output voltage can be selected from 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V. The first voltage regulator output current is 1A, and the second voltage regulator output current is 1A. The second voltage regulator output voltage is adjustable.
The ST2L05 is specifically designed for data storage applications such as hard disks and CD/DVD drives. It integrates two independent voltage regulators, each capable of supplying 1A of output current. The device offers fixed output voltages of 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, or 3.3V, with one regulator optionally adjustable from 1.25V to V- - Vprop.
The component is available in three packages: PPAK, SPAK, and a new 8-pin surface-mount package named DFN (5x6mm). Key features include guaranteed output current of 1A per channel, +2% output tolerance at 25°C, internal power and thermal protection, and stability with low ESR capacitors. The typical dropout voltage is 1.1V when both outputs are delivering 1A.
