150mA, Low-Dropout Linear Regulator  
with Power-OK Output  
General Description  
Features  
The MAX8875 low-dropout linear regulator operates from  
a +2.5V to +6.5V input range and delivers up to 150mA.  
A P-channel MOSFET pass transistor allows its 85µA sup-  
ply current to remain independent of the load, making this  
device ideal for battery-operated portable equipment  
such as PCS phones, cellular phones, cordless phones,  
and modems.  
o Power-OK Output  
o Small Output Capacitor (1µF ceramic)  
o Preset Output Voltages ( 1ꢀ accuracꢁ)  
o Guaranteed 150mA Output Current  
o 85µA No-Load Supplꢁ Current  
o Low 110mV Dropout at 100mA Load (165mV at  
150mA load)  
The MAX8875 features a power-OK (POK) output that indi-  
cates when the output is out of regulation. The device is  
available in several preset output voltage versions: 5.0V,  
3.3V, 3.0V, 2.7V, 2.5V, or 1.5V. Other features include 1µA  
(max) shutdown current, short-circuit protection, thermal  
shutdown protection, and reverse-battery protection. The  
device comes in a miniature 5-pin SOT23 package.  
o Thermal-Overload and Short-Circuit Protection  
o Reverse-Batterꢁ Protection  
o 60dB PSRR at 100Hz  
o 1µA max Shutdown Current  
The MAX8875 is optimized for use with a 1µF ceramic out-  
put capacitor. For a pin-compatible, functionally equivalent  
device for use with a higher ESR output capacitor, see the  
MAX8885 data sheet.
