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 ind us try-s ta nd a rd ‘2982 a nd offe r a n imp rove d

♦ Pin-Compatible with the Industry-Standard ‘2982

♦ Low Output Noise: 30µV

RMS

♦ Low 55mV Dropout at 50mA Output

dropout voltage. Typical output noise is 30µV

, and

RMS

(165mV at 150mA output)

typical dropout is only 165mV at 150mA. The output

voltage is preset to voltages in the range of 2.5V to

5.0V, in 100mV increments.

♦ Low 85µA No-Load Supply Current

♦ Low 100µA Operating Supply Current

Designed with an internal P-channel MOSFET pass

tra ns is tor, the MAX8877/MAX8878 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 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 a miniature 5-pin SOT23 package.

(even in dropout)

♦ Thermal-Overload and Short-Circuit Protection

♦ Reverse Battery Protection

♦ Output Current Limit

♦ Preset Output Voltages (±1.4% Accuracy)

♦ 10nA Logic-Controlled Shutdown
