This datasheet also covers the AX6644 variant, as both devices belong to the same dual channel ldo regulators family and are provided as variant models within a single manufacturer datasheet.
General Description
The AX6644/5 is a high accurately, low noise, high ripple rejection ratio, low dropout, dual CMOS LDO voltage regulators with enable function.
The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption.

tely, low noise, high ripple rejection ratio, low dropout, dual CMOS LDO voltage regulators with enable function. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. The AX6644/5 has the soft start function to suppress the inrush current. The current limit is over 250mA per channel and also operates as a short protection for the output current limiter. The output voltage for each regulator is set independently by internal setting. The AX6644/5 is fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability.
