APL5523KA

APL5523 Dual-Channel, 3.3V/500mA and 1.8V/300mA Linear Regulator Features • Fixed Output Voltage : VOUT1=3.3V/500mA VOUT2=1.8V/300mA Low Dropout Voltage (defined as the minimum input/output voltage difference): Output 1 Dropout Voltage : 0.6V (at 500mA) Output 2 Dropout Voltage : 0.9V (at 300mA) Stable with 4.7uF Output Capacitor(at VOUT1) Stable with 2.2uF Output Capacitor(at VOUT2) Built in Thermal Protection Built in Current Limit Protection Fast transient Response Short Setting Time SOP-8 and SOP-8-P Package Available General Description The APL5523 is a dual low dropout regulator with output1 with 3.3V/0.5A and output2 with 1.8V/0.3A output capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the APL5223 has been optimized. The dropout voltages are guaranteed at 0.6V at 0.5A for output1 and 0.9V at 0.3A for output 2. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The APL5523 regulator comes in a SOP-8 and SOP-8-P package. • • • • • • • Pin Configuration SOP−8 (Top View) V O UT1 SOP-8-P (Top View) V O UT1 1 2 3 4 8 7 6 5 Applications V GND GND GND GND 1 2 3 4 8 7 6 5 NC GND NC NC V V IN V V V IN IN IN O UT2 O UT2 • • • Desktop Computer Networking Systems Optical Data Storage Systems = Thermal Pad (connected to GND plane for better heat dissipation) Ordering and Marking Information APL5523 L e ad F re e C o d e H a n d lin g C o d e T e m p.
