General 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.
