Low-Noise, Low-Dropout,

150mA Linear Regulators in SOT23

_______________General Description

____________________________Features

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

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.

ꢀ Low 85µA No-Load Supply Current

ꢀ Low 100µA Operating Supply Current

(even in dropout)

Designed with an internal P-channel MOSFET pass

transistor, 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 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)
