General Description
The MAX8863T/S/R and MAX8864T/S/R low-dropout linear regulators operate from a +2.5V to +6.5V input range and deliver up to 120mA. A PMOS pass transistor allows the low, 80µA supply current to remain independent of load, making these devices ideal for battery-operated portable equipment such as cellular phones, cordless phones, and modems.

FEATUREs
♦ Low Cost
♦ Low, 55mV Dropout Voltage @ 50mA IOUT
♦ Low, 68µA No-Load Supply Current Low, 80µA Operating Supply Current (even in dropout)
♦ Low, 350µVRMS Output Noise
♦ Miniature External Components
♦ Thermal Overload Protection
♦ Output Current Limit
♦ Reverse Battery Protection
♦ Dual Mode™ Operation: Fixed or Adjustable (1.25V to 6.5V) Output
♦ Low-Power Shutdown
