ILC7010
Preliminary
80mA SC70 Ultra Low Noise CMOS RF-LDO鈩?Regulator
General Description
The ILC7010 is an 80mA, Ultra Low Noise, Low Dropout
(LDO) linear regulator, designed and processed in Impala鈥檚
proprietary CMOS process technology. This process com-
bines 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 cur-
rent 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 20碌V
RMS
and 1% output voltage accura-
cy, the ILC7010 sets a new standard in linear regulators for
communications and personal electronics applications.
The ILC7010 is designed to operate with small, low cost
ceramic capacitors and is stable over a wide range of ESR
values. In addition to the output capacitor, the ILC7010
requires only a 1碌F input capacitor. The enable pin can
be tied to V
IN
for easy device layout. The ILC7010 is avail-
able in a number of fixed output voltages ranging from
2.5V to 8V. An adjustable version will be available short-
ly. For competitive replacements, the ILC7080 is available
in a variety of pinout options in a SOT-23 package. The
ILC7080 offers the same operating characteristics and
features as the ILC7010
The ILC7010 is ideally suited for use in small size cordless
and cellular handsets as well as many other low battery
powered electronic devices. Please contact Impala for
samples and application information.
