ILC7080/81
50/100mA SOT-23 CMOS RF LDO™ Regulators
General Description
The ILC7080/81 are 50 or 100mA low dropout (LDO) volt-
age regulators designed to provide a high performance
solution to low power systems.
The devices offer 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 devices have been optimized to meet the needs of
modern wireless communications design; Low noise, low
dropout, small size, high peak current, high noise immuni-
ty. The ILC7080/81 are designed to make use of low cost
ceramic capacitors while outperforming other devices that
require tantalum capacitors.
Features
• Ultra low 1mV dropout per 1mA load
• 1% output voltage accuracy
• 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
• Less than 80µV
RMS
noise at BW = 100Hz to 100kHz
• Excellent line and load transient response
• Over current / over temperature protection
• Guaranteed up to 80/150mA output current
• Industry standard five lead SOT-23 package
• Fixed 2.85V, 3.0V, 3.3V, 3.6V, 4.7V, 5.0V and adjustable
output voltage options
• Metal mask option available for custom voltages between
2.5 to 10V
