The MAX8867/MAX8868 low-noise, low-dropout linear
regulators operate from a 2.5V to 6.5V input and deliver
up to 150mA. Typical output noise for these devices is
just 30µV
150mA. The output voltage is preset to voltages in the
range of 2.5V to 5.0V, in 100mV increments. The
MAX8867 and MAX8868 are pin-compatible with the
MAX8863 and MAX8864, except for the BP pin.
Designed with an internal P-channel MOSFET pass tran-
sistor, the MAX8867/MAX8868 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 thermal-
shutdown protection, and reverse battery protection.
The MAX8868 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 packages.
