General Descriptions
The AP139 is a positive voltage linear regulator
utilizing CMOS technology. The features that
include low quiescent current (45μA typ.), low
dropout voltage, and high output voltage accuracy,
make it ideal for battery applications. EN input
connected to CMOS has low bias current. The
space-saving SOT23-5L and TSOT23-5L package
is attractive for “Pocket” and “Hand Held”
applications.
This rugged device has both thermal shutdown, and
current limit protections to prevent device failure
under the “Worst” operating conditions.
In a low noise, regulated supply application, a 10nF
capacitor is necessary to be placed in between
Bypass and Ground.
The AP139 is stable with a low ESR output
capacitor of 1.0μF or greater.
