ST1L05A Very low quiescent BiCMOS voltage regulator

The ST1L05 family is a low drop linear voltage regulator capable of supplying up to 1.3 A output current.

The output voltage is fixed at 1.8 V, 2.5 V, 3.3 V and adjustable. It is available in three different versions with different pin outs.

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 especially suitable for data storage applications such as HDDs, where it can be used to supply the 3.3 V required by read channel and memory chips.

The regulator is available in the small and thin DFN6 (3 x 3) and DFN8 (4 x 4) packages
