ILC7011
Preliminary
80mA SC70 Ultra Low Noise CMOS RF-LDO™ Regulator
General Description
Features
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
10µVRMS and 1% output voltage accuracy, the ILC7011 sets
a new standard in linear regulators for communications and
personal electronics applications.
• 1% output voltage accuracy
• Only 10µVRMS noise from 300Hz to 100kHz
• Uses low ESR ceramic or Tantalum output capacitor to
minimize noise and output ripple.
• Only 90µA ground current at 80mA load
• Ripple rejection up to 70dB at 1kHz, 60dB at 1MHz
• Excellent line and load transient response
• Guaranteed to 80mA output current
• Industry standard five lead SC70 packages
• Fixed 2.8V, 3.0V, 3.3V, 3.6V, 4.7V, 5.0V, output voltage
options
• Metal mask option available for custom voltages between
2.5V and 8V
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 VIN 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.

Note 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.
Note 2: Specified Min/Max limits are production tested or guaranteed through correlation based on statistical control methods. Measurments are taken at constant junction
temperature as close to ambient as possible using low duty pulse testing.
Note 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.
Note 4: Guaranteed by design
Note 5: The device’s shutdown pin inlcudes a 2MΩ internal pull down resistor connected to ground.
