The output voltage is adjustable by external divider resistors, and the low feedback voltage of 410m V reduces the power consumption of the external sampling resistors, the EN pin supports TTL ON/OFF, and the built in output overvoltage protection and thermal shutdown protection. Suitable for very low quiescent current and ultrasmall size applications.
