General Description

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 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 ILC7010 offers a quiescent current 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 20µVRMS and 1 output voltage accuracy, the ILC7010 sets a new standard in linear regulators for communications and personal electronics applications.
