__________________General Description
The MAX8877/MAX8878 low-noise, low-dropout linear
regulators operate from a 2.5V to 6.5V input and deliver
up to 150mA. These devices are pin-compatible with
the industry-standard '2982 and offer an improved
dropout voltage. Typical output noise is 30VRMS, and
typical dropout is only 165mV at 150mA. The output
voltage is preset to voltages in the range of 1.5V to
5.0V, in 100mV increments.
Designed with an internal P-channel MOSFET pass
transistor, the MAX8877/MAX8878 maintain a low
100A supply current, independent of the load current
and dropout voltage. Other features include a 10nA
logic-controlled shutdown mode, short-circuit and ther-
mal-shutdown protection, and reverse battery protec-
tion. The MAX8878 also includes an auto-discharge
function, which actively discharges the output voltage
to ground when the device is placed in shutdown. Both
devices come in regular and thin 5-pin SOT23 pack-
ages.
