DESCRIPTION：
The SCT71203Fxx series products is a low-dropout linear regulator designed to operate with a wide input-voltage range from 3 V to 28 V (32V transient input voltage) and 300mA output current with enable control andPower-Good feature. The SCT71203Fxx 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 loadmakes the SCT71203Fxx 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 SCT71203Fxx 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 SCT71203Fxx series products integrated short-circuitand overcurrent protection, which makes the device more reliable during transient high-load current faults or shorting events.The SCT71203Fxx series products provide fixed 3.3V and 5V output voltage versions.The SCT71203Fxx series products is available in SOT23-
