SCT71403Q系列：3V-40V电压输入，300mA 2.4uA输出，带PG功能的低压差稳压器

The SCT71403Qseries products is a low-dropout linear  regulatordesigned to operate with a wide input-voltage range from 3 Vto 40 V (45V transient input voltage) and  300mA outputcurrent with enable control and PowerGood feature.The SCT71403Q series products is stable  with3.3uF~220uF output capacitors, and 10uF ceramic capacitor isrecommended. Only 2.4-µAtypical quiescent current at light load makes the SCT71403Qseries products ideal choices for  portabledevices with battery power supply and an  optimalsolution for powering microcontrollers (MCUs) and CAN/LINtransceivers in always-on systems. The SCT71403Qseries products implements power  good circuit(PG) which indicates that output voltage is in regulation.This signal could be used for power  sequencing oras a microcontroller reset. The SCT71403Qseries products integrated short-circuit andovercurrent protection with OCFB(Over Current Foldback) feature,which makes the device more reliable  duringtransient high-load current faults or shorting events.The SCT71403Qseries products provide fixed 3.3V and  5V outputvoltage versions, and also could provide 1.2V, 1.8V, 2.5V,3V, 4.2V and 4.5V fixed output voltage  versions,please contact SCT sales if needed. The SCT71403Qseries products is available in  SOT23-5,TDFN2x2-6, TDFN3x3-8, eMSOP3x3-8 and SOT223-4packages, for other package options, please contact SCTsales.
