Overview
MAX8863T/S/R, MAX8864T/S/R Low-Dropout, 120mA Linear Regulators 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.
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.
