DESCRIPTION：
DESCRIPTION：
The SCT71403A05Q series products is a low-dropout linear regulator designed to operate with a wide inputvoltage range from 3V to 40V and 300mA output current with enable control feature. The SCT71403A05Q series products is stable with 3.3uF~220uF output capacitors, and 10uF ceramic capacitor is recommended.Only 2.5μA typical quiescent current at light load makes the SCT71403A05Q 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 SCT71403A05Q series products integrated shortcircuit and overcurrent protection with VIN_HIGH Control feature, which makes the device more reliable during transient high-load current faults or shorting events. The SCT71403A05Q series products provide adjustable output version which can adjust the output voltage from 0.65V to 25V. The SCT7140Q series products is available in EMSOP-8 packages, for other package options, please contact SCT sales.
