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.
