DESCRIPTION：
The SCT71005Fxx series products is a low-dropout linear regulator designed to operate with a wide input-voltage range from 1.7 V to 6 V and 500mA output current with enable control and Power-Good feature. The SCT71005Fxx series products is stable with 2.2uF~220uF output capacitors, and 10uF ceramic capacitor is recommended.
Only 8-µA typical quiescent current at light load makes the SCT71005Fxx series products ideal choices for portable devices with battery power supply and an optimal solution for powering microcontrollers (MCUs) and CAN/LIN transceivers in always-on systems.
The SCT71005Fxx series products implements power good circuit (PG) which indicates that output voltage is in regulation. This signal could be used for power sequencing or as a microcontroller reset.
The SCT71005Fxx series products integrated short-circuit and overcurrent protection with OCFB (Over Current Fold-back) feature, which makes the device more reliable during transient high-load current faults or shorting events.
The SCT71005Fxx series products provide fixed 1.2V,1.8V and 3.3V output voltage versions.
The SCT71005Fxx series products is available in SOT23-5, TDFN2x2-6 and DFN1x1-4 packages.
