General Description
The ILC7010/7011 is an 80mA, Ultra 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,
ultra low noise and power handling capability. The ILC7010/
7011 offers a quiescent current of less than 100
µ
A, a logic
level enable (regulator EN) pin, a footprint that is half 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 40µV RMS and 1% output
voltage accuracy, the ILC7010/7011 sets a new standard in
linear regulators for communications and personal
electronics applications.

Notes:
1. For 2.5V < V
OUT
< 2.8V refer to diagram “Dropout Voltage vs. Output Voltage.”
2. Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2% below the nominal
value measured with 1V differential.
