ST2L05-3300
Very low quiescent current dual voltage regulator
Features
■ V_O1: fixed
■ V_O2: adjustable from 1.25 to V_I - V_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_O1 = I_O2 = 1 A)
■ 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
DFN8 (5x6 mm)
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.
Applications
■ Hard disk drives
■ CD/DVD-ROMs
■ CD/DVD-R/RWs
■ COMBO^® (DVD-ROM+CD-R/RW)
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,
2.8 V and 3.0 V. The other is adjustable from 1.25
V to V_I - V_DROP, which is suitable for powering
several different types of microcontroller. Both
outputs are current-limited
