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 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.
