ST2L05R3300PS Description

Short technical summary and product information.

The STMicroelectronics ST2L05R3300PS is a dual-output linear voltage regulator designed for applications such as data storage devices. It integrates two voltage regulators, each capable of supplying up to 1A.

 

One regulator output can be fixed to specific voltages like 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, or 3.3V, depending on the version. The second regulator can be set to the same fixed voltages or be adjustable from 1.25V to V I - VDROP, allowing flexibility for powering various micro-controllers.

 

Key features include internal power and thermal limiting, stability with low ESR output capacitors, and a wide operating temperature range of 0°C to 125°C. The device is available in an 8-pin DFN (5x6mm) surface-mount package.

 

Applications include hard disk drives, CD/DVD-ROM, CD/DVD-R/RW, and COMBO drives.
