产品概述
描述
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.
