General Description
The ILC7071 is an 100mA, Low Noise, Low Dropout
(LDO) linear regulator, designed and processed 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
noise 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 noise of 40µ
V_RMS and 1% output voltage accuracy, the ILC7071 is
ideally suited for communications and personal electronics
applications.
