Description
The ILC7083/ILC7084 is a 150mA low dropout (LDO)
voltage regulator designed to provide a high performance
solution to low power systems. The device offers 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 device has been optimized to meet the needs of modern
wireless communications design; Low noise, low dropout,
small size, high peak current, high noise immunity.
The ILC7083/ILC7084 is designed to make use of low cost
ceramic capacitors while outperforming other devices that
require tantalum capacitors.
As opposed to ILC7084, the ILC7083 has a built in output
capacitor discharge circuit active in shutdown mode. This
feature is necessary in applications where the output voltage
must decrease quickly to zero volt in shutdown mode.
