Description
The ILC7080/81 are 50 or 100mA low dropout (LDO)
voltage regulators designed to provide a high performance
solution to low power systems.
The devices offer a typical combination of low dropout and
low quiescent current expected of CMOS parts, while
uniquely providing the low noise and high ripple rejection
characteristics usually only associated with bipolar LDO
regulators.
The devices have been optimized to meet the needs of
modern wireless communications design; Low noise, low
dropout, small size, high peak current, high noise immunity.
The ILC7080/81 are designed to make use of low cost
ceramic capacitors while outperforming other devices that
require tantalum capacitors.
