General Description
The dual LDO PAM3102 series of positive voltage
linear regulators feature high output voltage
accuracy, low quiescent current and low dropout
voltage, making them ideal for battery powered
applications. The line transient response and load
transient response are excellent. Their high PSRR
make them useful in applications where AC noise
on the input power supply must be suppressed.
Space-saving SOT23-6 package for 2-ch LDOs is
attractive for portable and handheld applications.
They have both thermal shutdown and a current
limit feature to prevent device failure under
extreme operating conditions. They are stable
with an output capacitance of 2.2μF or greater.
