ST1L02xx Very low quiescent BiCMOS voltage regulator Features ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Fixed output voltage: 1.8 V, 2.5 V, 3.3 V (1.5 V, under customer request) Output voltage tolerance: ± 2 % at 25 °C Output current capability: 1 A minimum Very low quiescent current: max 500 A over temperature range Typ. dropout 0.7 V (@ IO = 1 A) Stable with low ESR ceramic capacitors Available with and without the external output voltage sense pin Thermal shutdown protection with hysteresis Over current protection Operating junction temperature range: from 0 to 125 °C 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. DFN6D (3x3 mm) Description 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 A over the whole allowed junction temperature range. The ST1L02xx is stable with low ESR output ceramic capacitors. Table 1. Device summary Part numbers ST1L02XX18 ST1L02XX25 ST1L02XX33 ST1L02XX 1.
