Overview

  • Low Cost
  • Low, 55mV Dropout Voltage at 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

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.

The devices feature Dual Mode™ operation: their output voltage is preset (at 3.15V for the T versions, 2.84V for the S versions, or 2.80V for the R versions) or can be adjusted with an external resistor divider. Other features include low-power shutdown, short-circuit protection, thermal shutdown protection, and reverse battery protection. The MAX8864 also includes an auto-discharge function, which actively discharges the output voltage to ground when the device is placed in shutdown mode. Both devices come in a miniature 5-pin SOT23 package.
