SCT71203 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) 300mA output current with enable control Power-Good feature. The SCT71203 series products is stable with 3.3uF~220uF output capacitors, 10uF ceramic capacitor is recommended.Only 2.4-μA typical quiescent current at light load makes the SCT71203 series products ideal choices for portable devices with battery power supply anoptimal solution for powering microcontrollers (MCUs) CAN/LIN transceivers in always-on systems.The SCT71203 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 SCT71203 series products integrated short-circuit overcurrent protection, which makes the device more reliable during transient high-load current faults or shorting events.The SCT71203 series products provide fixed 3.3V 5V output voltage versions, also could provide 1.2V, 1.8V, 2.5V, 3V, 4.2V 4.5V fixed output voltage versions, please contact SCT sales if needed.The SCT71203 series products is available in SOT23-5 package, for other package options, please contact SCT sales.
