DESCRIPTION：

The SCT71403Fxx series products is a low-dropout linear regulator designed to operate with a wide input-voltage range from 3 V to 40 V (45V transient input voltage) and 300mA output current with enable control and Power-Good feature. The SCT71403Fxx series products is stable with 3.3uF~220uF output capacitors, and 10uF ceramic capacitor is recommended.
Only 2.4-µA typical quiescent current at light load makes the SCT71403Fxx 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 SCT71403Fxx 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 SCT71403Fxx 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 SCT71403Fxx series products provide fixed 3.3V and 5V output voltage versions.
The SCT71403Fxx series products is available in SOT23-5, TDFN2x2-6, TDFN3x3-8 and eMSOP3x3-8 packages.
