APL5525/5526
Dual Channel 500mA Regulator + Reset IC
Features
* * Low Quiescent Current : 130A (No load) Low Dropout Voltage : VDROP1=550mV@500mA VDROP2=630mV@500mA Fixed Output Voltage : VOUT1=3.3V/500mA VOUT2=2.5V/500mA Stable with 4.7F Output Capacitor Stable with Aluminum, Tantalum or Ceramic Capacitors Reverse Current Protection No Protection Diodes Needed Built in Thermal Protection Fast Transient Response Short Setting Time SOP-8, SOP-8-P with Thermal Pad Packages Adjustment-free Reset Detection Voltage : 3.9V or 4.2V typ Easy to Set Delay Time from Voltage Detection to Reset Release
General Description
The APL5525/6 is a dual-channel regulator with reset function (specific voltage monitoring), and internal delay circuit, set to detect 3.9V or 4.2V. Maximum input voltage is 6V, output1 and output2 deliver up to 500mA. VOUT1 typical dropout voltage is 550mV at 500mA loading and VOUT2 typical dropout voltage is 630mV at 500mA loading. Design with an internal Pchannel MOSFET pass transistor, the APL5525/6 maintains a low supply current. Other features include, thermal-shutdown protection, current limit protection to ensure specified output current. The APL5525/6 come in miniature SOP-8 and SOP-8-P packages.
