Low-Noise, Low-Dropout, 150mA Linear  
Regulators with '2982 Pinout  
__________________General Description  
____________________________Features  
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  
ꢀ Pin-Compatible with the Industry-Standard '2982  
ꢀ Low Output Noise: 30µV

ꢀ 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 1.5V 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  
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.
