ILC7011
Preliminary 80mA SC70 Ultra Low Noise CMOS RF-LDOTM Regulator
General Description 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 100A, 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 10VRMS 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 1F 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. The ILC7011 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.

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 2M internal pull down resistor connected to ground.
