Impala Linear Corporation 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 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 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. 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 in a number of fixed output voltages ranging from 2.5V to 8V. An adjustable version will be available shortly. • 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 Applications • • • • Cellular phones Wireless communicators PDAs / palmtops / organizers Battery powered portable electronics The ILC7071 is ideally suited for use in small size cordless and cellular handsets as well as many other low battery powered electronic devices.

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.
