ST1L02 Very low quiescent current BiCMOS voltage regulator Datasheet - production data The ST1L02 is suitable for data storage applications such as HDDs, where it can be used to supply the read channel and memory chips requiring 3.3 V. The regulator is available in the small and thin DFN6 (3x3 mm) package. DFN6 (3x3 mm) Table 1. Device summary Order code Package Features ST1L02PU18R DFN6 (3x3 mm) Fixed output voltages: 1.8 V, 2.5 V, 3.3 V (1.5 ST1L02PU33R DFN6 (3x3 mm) V, upon customer request) Output voltage tolerance: 2% at 25 C Output current capability: 1 A minimum Very low quiescent current: max. 500 A overtemperature range Typical dropout voltage 0.7 V ( I = 1 A) O Stable with low ESR ceramic capacitors Thermal shutdown protection with hysteresis Overcurrent protection Operating junction temperature range: from 0 to 125 C Description The ST1L02 is a low drop linear voltage regulator, which supplies up to 1 A output current. It is available in several fixed output voltage versions. Thanks to BiCMOS technology, quiescent current is well-controlled and maintained below 650 A over the whole allowed junction temperature range. The ST1L02 is stable with low ESR output ceramic capacitors. Internal protection circuitry includes thermal protection with hysteresis and overcurrent limiting.
