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 criti-
cal for low voltage applications, the APL5223 has
been optimized. The dropout voltages are guaran-
teed at 0.6V at 0.5A for output1 and 0.9V at 0.3A for
output 2. Current limit is trimmed to ensure speci-
fied output current and controlled short-circuit current.
On-chip thermal limiting provides protection against
any combination of overload that would create ex-
cessive junction temperatures. The APL5523 regu-
lator comes in a SOP-8 and SOP-8-P package.
Applications
• Desktop Computer
• Networking Systems
• Optical Data Storage Systems
• 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
