Description

The 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.
