General Description

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.
