APL5522
Dual-Channel, 3.3V/500mA and 2.5V/500mA Linear Regulator
Features
General Description
•
The APL5522 is a dual low dropout regulator with output
1 with 3.3V/0.5A and output2 with 2.5V/0.5A output
Fixed Output Voltage :
VOUT1=3.3V/500mA (within Maximum Power
Dissipation)
capability. In order to obtain lower dropout voltage and
faster transient response, which is critical for low voltage
VOUT2=2.5V/500mA (within Maximum Power
applications, the APL5522 has been optimized. VOUT1 typical dropout voltage is 550mV at 500mA loading and VOUT2
Dissipation)
•
Low Dropout Voltage (Defined as the Minimum
typical dropout voltage is 630mV at 500mA loading. Current limit is trimmed to ensure specified output current
Input/Output Voltage Difference):
Output 1 Dropout Voltage : 550mV (at 500mA)
and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of over-

(The thermal pad of SOP-8P has to be connected
to the GND plane to get better heat dissipation
than SOP-8.)

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
