The ISL80121-5 is a low dropout voltage, single output LDO with
programmable current limiting.
This LDO operates from input voltages of 2.2V to 6V. The ISL80121-5
has a nominal output
voltage of 5V. Other custom voltage options are available upon
request.
A sub-micron BiCMOS process is utilized for this product family to
deliver the best in class analogperformance and overall value. The
programmable current limiting improves system reliability of end
applications. An external capacitor on the soft-start pin provides
an adjustable soft-starting ramp. The ENABLE feature allows the
part to be placed into a low quiescent current
shutdown mode.
