Product overview
Description
The ST1L02 is a low drop linear voltage regulator, which supplies up to 1 A output current.
It is available in several fixed output voltage versions. Thanks to BiCMOS technology, quiescent current is well-controlled and maintained below 650 μA over the whole allowed junction temperature range.
The ST1L02 is stable with low ESR output ceramic capacitors.
Internal protection circuitry includes thermal protection with hysteresis and overcurrent limiting.
The ST1L02 is suitable for data storage applications such as HDDs, where it can be used to supply the read channel and memory chips requiring 3.3 V.
The regulator is available in the small and thin DFN6 (3x3 mm) package.
