ST1L05Very low quiescent current BiCMOS voltage regulator
Datasheet - production data
Features Fixed output voltage: 1.8 V, 2.5 V, 3.3 V and
ADJ Output voltage tolerance: ± 2% at 25 °C Output current capability: 1.3 A Very low quiescent current: max. 650 µA Typ. dropout 0.3 V (@ IO = 1.3 A) Enable function for B, C and D versions Power Good function for B and D versions Stable with low ESR ceramic capacitors Thermal shutdown protection with hysteresis Overcurrent protection Operating junction temperature range: from 0
to 125 °C
DescriptionThe ST1L05 is a low drop linear voltage regulator,
which supplies up to 1.3 A output current.
The output voltage is fixed at 1.8 V, 2.5 V, 3.3 V
and it is adjustable. It is available in three different
versions with different pinouts.
Thanks to BiCMOS technology, the quiescent
current is controlled and maintained below
650 µA over the entire allowed junction
temperature range. The ST1L05 is stable with low
ESR output ceramic capacitors.
Internal protection circuitry includes thermal
protection with hysteresis and overcurrent
limiting.
The ST1L05 is suitable for data storage
applications such as HDDs, where it can supply
3.3 V required by read channel and memory
chips.
The regulator is available in the small and thin
DFN6 (3x3 mm) and DFN8 (4x4 mm) packages.
