Features
General Description
The APL5521 is a dual low dropout regulator with
output 1 with 3.3V/0.5A and output2 with 2.5V/0.3A
output capability. In order to obtain lower dropout
voltage and faster transient response, which is criti-
cal for low voltage applications, the APL5221 has
been optimized. The dropout voltages are guaran-
teed at 1.25V at 0.5A for output1 and 1.2V 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 APL5521 regu-
lator comes in a SOP-8 package.
