Advanced Power Electronics Corp. APE8843 DUAL 600mA LDO REGULATOR WITH ENABLE FUNCTION FEATURES DESCRIPTION The APE8843 is an efficient, precise dual-channel CMOS LDO regulator optimized for ultra-low-quiescent applications. Regulators output1 and output2 are capable of sourcing 600mA of output current. The regulators are stable with output capacitors as low as 1uF, including current limit, thermal shutdown protection, fast transient response, low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio. The APE8843 regulators are able to support individual On/Off function. The APE8843 regulators are available in used ESOP-8 package. Input Voltage Range : Channel 1 : 4.2V to 6V Channel 2 : 3.2V to 6V Low Quiescent Current is 30uA/per Channel (typ.) Tight Load and Line Regulation Fast Transient Response Current Limit and Thermal Shutdown Protection Only low-ESR Ceramic Capacitors Required for Stability Available in the ESOP-8 Pb-Free Package Halogen Free Product TYPICAL APPLICATION APE8843 VIN1 VIN1 C1 ON 1uF ON EN1 EN2 OFF OFF VOUT1 C2 1uF VIN2 VIN2 VOUT1 C3 1uF VOUT2 C4 1uF VOUT2 GND PACKAGE / ORDERING INFORMATION APE8843 X – X Package MP : ESOP - 8 ( Top View ) VIN1 1 8 EN1 Output voltage A : VOUT1 =3 .3 V, V OUT2=1.2V B : VOUT1 =2.5V, V OUT2=1.2V C : VOUT1 =1.2V, V OUT2=1.1V VOUT1 2 VIN2 3 7 GND GND VOUT2 4 6 GND 5 EN2 ESOP-8 Data and specifications subject to change without notice 1 20130111V1.1 Advanced Power Electronics Corp.
