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

♦ Low Output Noise: 30µV

RMS

♦ Low 55mV Dropout at 50mA Output

(165mV at 150mA output)

just 30µV

, and typical dropout is only 165mV at

RMS

150mA. The output voltage is preset to voltages in the

ra ng e of 2.5V to 5.0V, in 100mV inc re me nts . The

MAX8867 and MAX8868 are pin-compatible with the

MAX8863 and MAX8864, except for the BP pin.

♦ Low 85µA No-Load Supply Current

♦ Low 100µA Operating Supply Current

(even in dropout)

Designed with an internal P-channel MOSFET pass

tra ns is tor, the MAX8867/MAX8868 ma inta in 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 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 a miniature 5-pin SOT23 package.

♦ Thermal-Overload and Short-Circuit Protection

♦ Reverse Battery Protection

♦ Output Current Limit

♦ Preset Output Voltages (±1.4% accuracy)

♦ 10nA Logic-Controlled Shutdown
