The MAX8874 also includes an auto-discharge function, which actively discharges the output voltage to ground when the device is placed in shutdown mode. Other features include low-power shutdown, short-circuit protection, thermal shutdown protection, and reverse battery protection. Output voltages are set on the low side of popular ranges so that power drain is minimized for longer battery life. 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. A PMOS pass transistor allows the low, 82♚ supply current to remain independent of load, making these devices ideal for battery-operated portable equipment such as cellular phones and cordless phones. The MAX8873T/S/R and MAX8874T/S/R low-dropout linear regulators operate from a +2.5V to +6.5V input range and deliver up to 120mA.
