MAX8863T/S/R, Low-Dropout, 120mA Linear Regulators MAX8864T/S/R General Description Benefits and Features
The MAX8863T/S/R and MAX8864T/S/R low-dropout linear ● Low Cost regulators operate from a +2.5V to +6.5V input range and ● Low, 55mV Dropout Voltage at 50mA I deliver up to 120mA. A PMOS pass transistor allows the OUT low, 80μA supply current to remain independent of load, ● Low, 68μA No-Load Supply Current making these devices ideal for battery-operated portable Low, 80μA Operating Supply Current (even in equipment such as cellular phones, cordless phones, and dropout) modems. ● Low, 350μVRMS Output Noise The devices feature Dual Mode™ operation: their output ● Miniature External Components voltage is preset (at 3.15V for the T versions, 2.84V for ● Thermal Overload Protection the S versions, or 2.80V for the R versions) or can be adjusted with an external resistor divider. Other features ● Output Current Limit include low-power shutdown, short-circuit protection, thermal ● Reverse Battery Protection shutdown protection, and reverse battery protection. The ● Dual Mode Operation: Fixed or Adjustable MAX8864 also includes an auto-discharge function, which (1.25V to 6.5V) Output actively discharges the output voltage to ground when the device is placed in shutdown mode. Both devices come in ● Low-Power Shutdown a miniature 5-pin SOT23 package.
