General Description
The ILC7071 is an 100mA, Low Noi, Low Dropout (LDO) linear regulator, designed and procesd in CMOS 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, low noi and power handling capability. The ILC7071 offers a quiescent current of less than 100µA, a logic level enable (regulator EN) pin, the size of the industry standard SOT-23 and a low dropout voltage of 25mV at 10mA. With better than 70 dB (1kHz) of ripple rejection, low noi of 40µ V RMS and 1% output voltage accuracy, the ILC7071 is ideally suited for communications and personal electronics applications.
