Anpec APL5523K Dual-channel, 3.3v/500ma and 1.8v/300ma linear regulator Datasheet

APL5523
Dual-Channel, 3.3V/500mA and 1.8V/300mA Linear Regulator
Features
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.
•
•
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)
