ILC7071
100mA SOT-23-5 Ultra Low Noise
CMOS RF-LDO™ Regulator
General Description
Features
The ILC7071 is a 100mA, Ultra Low Noise, Low Dropout
(LDO) linear regulator, designed and processed in Impala’s
proprietary CMOS process technology. This process com-
bines the best CMOS features of low quiescent current,
small size and low dropout voltage with the best bipolar fea-
tures of high ripple rejection, ultra low noise and power han-
dling capability. The ILC7071 offers a quiescent current of
less than 100µA, a logic level enable (regulator on/off) pin,
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 ILC7071
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 100mA load
• Ripple rejection up to 70dB at 1kHz, 60dB at 1MHz
• Excellent line and load transient response
• Guaranteed to 100mA output current
• Industry standard five lead SOT-23-5 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 ILC7071 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 ILC7071
requires only a 1µF input capacitor. The enable pin can be
tied to VIN for easy device layout. The ILC7071 is available
Applications
• Cellular phones
• Wireless communicators
• PDAs / palmtops / organizers
• Battery powered portable electronics
in a number of fixed output voltages ranging from 2.5V to
8V. An adjustable version will be available shortly.
The ILC7071 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.

Note1: 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. Measurements 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 includes a 2MΩ internal pull down resistor connected to ground.
