Product Overview
ST2L05R3300PS is a very low quiescent current dual voltage regulator. It is specifically designed for data storage applications, this device integrates two voltage regulators, each capable of supplying 1A of current. The outputs are current-limited and overtemperature-protected. Also noteworthy is the very good thermal performance of the DFN package, with only 2°C/W of thermal resistance junction-to-case. Typical applications are hard disk drives, CD/DVD-ROMs, CD/DVD-R/RWs, COMBO® (DVD-ROM+CD-R/RW).
- Good stability with low ESR output capacitor
- Internal power and thermal limit
- ±3% output tolerance at overtemperature
- Operating temperature range from 0°C to 125°C
- Input voltage range from 4.5 to 7V
- Input voltage ripple is ±0.15V
- Input voltage rise time/fall time (from 10% to 90%) is ≥1µs
- DFN8 package
- Adjustable output voltage
- Guaranteed current of output 1 and output 2 is 1A
