Impala Linear Corporation 1(408) 574-3939 www.impalalinear.com August 2000 ILC7010 1.3 The ILC7010 is an 80mA, 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 features of high ripple rejection, ultra low noise and power handling capability. The ILC7010 offers a quiescent cur- rent of less than 100mA, 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 20µV RMS and 1% output voltage accura- cy, the ILC7010 sets a new standard in linear regulators for communications and personal electronics applications. The ILC7010 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 ILC7010 requires only a 1µF input capacitor. The enable pin can be tied to V IN for easy device layout. The ILC7010 is avail- able in a number of fixed output voltages ranging from 2.5V to 8V. An adjustable version will be available short- ly. For competitive replacements, the ILC7080 is available in a variety of pinout options in a SOT-23 package. The ILC7080 offers the same operating characteristics and features as the ILC7010 The ILC7010 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.

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. Measur ements 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 nomina l 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.
