Description

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.

Features

• Ultra low 1mV dropout per 1mA load

• 3 output voltage accuracy

• Only 40µVRMS noise

• 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

• Metal mask option available for custom voltages between 2.5V and 5.1V

Applications

• Cellular phones

• Wireless communicators

• PDAs / palmtops / organizers

• Battery powered portable electronics
