Impala Linear Corporation ILC7071AIM5-47, ILC7071AIM5-36, ILC7071AIM5-33, ILC7071AIM5-30, ILC7071AIM5-50 Datasheet

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.

The ILC7071 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 ILC7071
requires only a 1µF input capacitor. The enable pin can be
tied to V

IN

for easy device layout. The ILC7071 is available

in a number of fixed output voltages ranging from 2.5V to
8V. An adjustable version will be available shortly.

The ILC7071 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.
