ILC7083/ILC7084

150mA SOT-23 Low Noise CMOS RF-LDO™

Regulator

Features

Description

• Ultra low 1mV dropout per 1mA load

• 3% output voltage accuracy

• Only 40µV_RMSnoise

• Uses low ESR ceramic output capacitor to minimize noise

and output ripple

• Only 100µA ground current at 100mA load

• Ripple rejection up to 85dB at 1kHz, 60dB at 1MHz

• Excellent line and load transient response

• Over current / over temperature protection

• Guaranteed to 150mA output current

• Industry standard ﬁve lead SOT-23 package

• Fixed 2.5V, 2.7V, 2.85V, 3.0V, 3.3V, 3.6V, 5V output

voltage for ILC7083 and adjustable output voltage for

ILC7083/ILC7084

The ILC7083/ILC7084 is a 150mA low dropout (LDO)

voltage regulator designed to provide a high performance

solution to low power systems. The device offers a typical

combination of low dropout and low quiescent current

expected of CMOS parts, while uniquely providing the low

noise and high ripple rejection characteristics usually only

associated with bipolar LDO regulators.

The device has been optimized to meet the needs of modern

wireless communications design; Low noise, low dropout,

small size, high peak current, high noise immunity.

The ILC7083/ILC7084 is designed to make use of low cost

ceramic capacitors while outperforming other devices that

require tantalum capacitors.

• Metal mask option available for custom voltages between

2.5V and 5.1V

As opposed to ILC7084, the ILC7083 has a built in output

capacitor discharge circuit active in shutdown mode. This

feature is necessary in applications where the output voltage

must decrease quickly to zero volt in shutdown mode.

Applications

• Cellular phones

• Wireless communicators

• PDAs / palmtops / organizers

• Battery powered portable electronics
