AX6636C Datasheet | AXElite

DESCRIPTION The AX6636A/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 600m A 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 AX6636A/B/C contains internal pull high enable function that allows the output of each regulator to be turned off independently. The AX6636A/B/C regulators are available in used SOP-8L with Exposed Pad package.  FEATURES - Input voltage range : Channel1: 3.4V to 5.5V Channel2: 2.8V to 5.5V - Low Quiescent Current is 50u A/per channel (typ.) - Fast transient response - Tight Load and Line Regulation - Current limit and thermal VÛmw`R- yÑb€ shutdown protection - Support Ceramic Capacitors and Aluminum Electrolytic Capacitors for Stability - Available in the SOP-8L with exposed pad Pb-Free Package w.goftechm  BLOCK DIAGRAM VIN2 VIN1 Current Limit2 Thermal Shutdown Bandgap Current Limit1 - - + + VOUT2 Error Amp Error Amp Enable2 Enable1 VOUT1 GND EN2 EN1 1/10 Axelite Confidential Materials, do not copy or distribute without written consent.
