__________________General Desc ription
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 30μV
RMS
, and
typical dropout is only 165mV at 150mA. The output
voltage is preset to voltages in the range of 2.5V to
5.0V, in 100mV increments.
Designed with an internal P-channel MOSFET pass
transistor, the MAX8877/MAX8878 maintain a low
100μA 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 a miniature 5-pin SOT23 package.
