AX6638

AX6638 Dual 700mA LDO Regulator with Enable Function  GENERAL DESCRIPTION The AX6638A/B/C is an efficient, precise dual-channel CMOS LDO regulator optimized for ultra-low-quiescent applications. Regulators output1 and output2 are capable of sourcing 700mA of output current. The regulators are stable with output capacitors as low as 1μF, including current limit, thermal shutdown protection, fast transient response, low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. The AX6638A/B/C contains internal pull high enable function that allows the output of regulator to be turned off. The AX6638A/B/C regulators are available in used TO252-5L Pb-Free package.  FEATURES Input voltage range : 3.4V to 5.5V Low Quiescent Current is 50uA/per channel (typ.) Fast transient response Tight Load and Line Regulation Current limit and thermal shutdown protection Only low-ESR Ceramic Capacitors Required for Stability Available in the TO252-5L Pb-Free Package  BLOCK DIAGRAM VÛmw`RyÑb€ w.goftechm Current Limit2 VIN Thermal Shutdown Bandgap Current Limit1 - - + + VOUT2 Error Amp Error Amp Enable VOUT1 GND EN 1/10 Axelite Confidential Materials, do not copy or distribute without written consent.
