APL5505/6/7
Features
General Description
The APL5505/6/7 is micropower, low noise , low drop-
out regulators with a reset function (regulator input
(APL5505) or specific voltage(APL5506/7) monitoring),
and internal delay circuit, set to detect 3.9V or 4.2V.
Operate from 3V to 6V input voltage and deliver up to
500mA. Typical output noise is just 180uV
RMS
with an
external 0.01uF bypass capacitor connected in BP
pin and the typical dropout voltage is only 300mV at
500mA loading. Design with an internal P-channel
MOSFET pass transistor, the APL5505/6/7 maintains
a low supply current, independent of the load current
and dropout voltage. Other features include reverse
current protection, thermal-shutdown protection, cur-
rent limit protection to ensure specified output current
and controlled short-circuit current. The APL5505/6/
7 regulators come in miniature SOP-8, TSSOP-8 and
MSOP-8 packages.
