ST1L02XX33 Very low quiescent BiCMOS voltage regulator

The ST1L02xx is a low drop linear voltage regulator capable to supply up to 1 A output current.

The output voltage is fixed to 3.3 V, but under customer request, it’s possible to have also 1.5 V, 1.8 V and 2.5 V. Thanks to the BiCMOS technology, the quiescent current is well controlled and maintained below 650 µA over the whole allowed junction temperature range.

The ST1L02xx is stable with low ESR output ceramic capacitors.

Internal protection circuitry includes thermal protection with hysteresis and over current limiting.

The ST1L02xx is especially suitable for data storage applications such as HDDs, where can be used to supply the read channel and memory chips requiring 3.3 V.

The regulator is available in the small and thin DFN6D (3x3 mm) package
