CMOS LOW DROPOUT REGULATORS
FSP2114
„ GENERAL DESCRIPTION
The FSP2114 is a high performance low dropout
voltage regulator designed for portable applications
with low quiescent current and low dropout voltage.
The FSP2114 has a typical current limit of 400mA and
is capable of delivering up to 250mA output current. It
is available in output voltages from 1.5V to 4V in 50mV
increments. It features current limit with fold-back in
short circuit.
The FSP2114 is available in SOT23-3L and SOT89-3L
packages. These products are ideal for portable
information devices, cellular phones, and other battery
powered applications.
