Dual, Low-Noise, Low-Dropout, 160mA Linear  
Regulators in SOT23  
General Description  
Features  
Two LDOs in Tiny SOT23  
The MAX8882/MAX8883 dual, low-noise, low-dropout  
linear regulators operate from a +2.5V to +6.5V input  
and deliver up to 160mA each of continuous current.  
Both versions offer low output noise and low dropout of  
only 72mV at 80mA. Designed with an internal P-  
channel MOSFET pass transistor, the MAX8882/  
MAX8883 maintain a low 165µA supply current (both  
LDOs on), independent of the load current and dropout  
voltage. Other features include short-circuit protection  
and thermal-shutdown protection. The MAX8882 has a  
single shutdown input and provides an external refer-  
ence bypass pin to improve noise performance. The  
MAX8883 includes two independent logic-controlled  
shutdown inputs. The MAX8882/MAX8883 are both  
available in a miniature 6-pin SOT23 package.
