Impala Linear Corporation ILC7011C5-50, ILC7011C5-47, ILC7011C5-33, ILC7011C5-30, ILC7011C5-28 Datasheet
...
The ILC7011 is an 80mA, Ultra Low Noise, Low Dropout
(LDO) linear regulator, designed and processed in Impala’s
proprietary CMOS process technology. This process combines the best CMOS features of low quiescent current,
small size and low dropout voltage with the best bipolar features of high ripple rejection, ultra low noise and power handling capability. The ILC7011 offers a quiescent current of
less than 100µA, a logic level enable (regulator on/off) pin,
a footprint that is half the size of the industry standard SOT23 and a low dropout voltage of 50mV at 10mA. With better than 70dB (1kHz) of ripple rejection, ultra low noise of
10µV
RMS
and 1% output voltage accuracy , the ILC7011 sets
a new standard in linear regulators for communications and
personal electronics applications.
The ILC7011 is designed to operate with small, low cost,
ceramic capacitors and is stable over a wide range of ESR
values. In addition to the output capacitor, the ILC7011
requires only a 1µF input capacitor. The enable pin can be
tied to V
IN
for easy device layout. The ILC7011 is available
in a number of fixed output voltages ranging from 2.5V to
8V. An adjacent version will be available shortly.
The ILC7011 is ideally suited for use in small size cordless
and cellular handsets as well as many other low battery
powered electronic devices. Please contact Impala for
samples and application information.
