Low-Noise, Low-Dropout, 150mA Linear

Regulators with '2982 Pinout

__________________General Description

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 1.5V 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 regular and thin 5-pin SOT23 pack-

ages.
