Description
The ILC7011 is an 80mA, Ultra Low Noise, Low Dropout
(LDO) linear regulator, designed and processed in Fairchild
Semiconductor’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 SOT-23 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.

Notes:
1: Absolute maximum ratings indicate limits which when exceeded may result in damage to the component. Electrical
specifications do not apply when operating the device outside of its rated operating conditions.
2: Specified Min/Max limits are production tested or guaranteed through correlation based on statistical control methods.
Measurements are taken at constant junction temperature as close to ambient as possible using low duty pulse testing.
3: Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2% below the nominal
value measured with a 1V differential.
4: Guaranteed by design
5: The device’s shutdown pin includes a 2MΩ internal pull down resistor connected to ground.
