ST2L05-3300 Very low quiescent current dual voltage regulator Datasheet - production data Description Specifically designed for data storage applications, this device integrates two voltage regulators, each capable of supplying 1 A of current. It is assembled in an 8-pin DFN8 5x6 mm surface mounting package. One regulator block supplies 3.3 V and, on request, 1.5 V, 1.8 V, 2.5 V, DFN8 (5x6 mm) 2.8 V and 3.0 V. The other is adjustable from 1.25 V to V - V , which is suitable for powering I DROP several different types of microcontroller. Both outputs are current-limited and overtemperature Features protected. Also noteworthy is the very good thermal performance of the DFN package, with V : fixed O1 only 2 C/W of thermal resistance junction-to- case. V : adjustable from 1.25 to V - V O2 I DROP Guaranteed current of output 1: 1 A Guaranteed current of output 2: 1 A 2% output tolerance (at 25 C) 3% output tolerance at overtemperature Typical dropout 1.1 V (I = I = 1 A) O1 O2 Internal power and thermal limit Good stability with low ESR output capacitor Operating temperature range: 0 C to 125 C Very low quiescent current: 7 mA max overtemperature Available in DFN8 5x6 mm package Applications Hard disk drives CD/DVD-ROMs CD/DVD-R/RWs COMBO (DVD-ROM+CD-R/RW) Table 1.
