Precision Shunt Regulators with Reset  
in SOT23-3  
________________General Description  
____________________________Features  
100µA to 50mA Shunt Current Range  
Low Cost  
The MAX6330/MAX6331 combine a precision shunt  
regulator with a power-on reset function in a single  
SOT23-3 package. They offer a low-cost method of  
operating small microprocessor (µP)-based systems  
from high-voltage sources, while simultaneously pro-  
tecting µPs from power-up, power-down, and brownout  
conditions.  
3-Pin SOT23 Package  
1.5% Tolerance on Output Voltage  
Three Shunt Voltages Available: 5V, 3.3V, 3.0V  
Both active-low (MAX6330) and active-high (MAX6331)  
push/pull output versions are available. The output  
voltage has 1.ꢀ5 tolerance. The MAX6330/MAX6331  
operate over a wide shunt current range from 100µA to  
ꢀ0mA, and offer very good transient immunity.  
Precision Power-On Reset Threshold:  
1.5% Tolerance Available with Either  
RESET (MAX6331) or RESET (MAX6330)  
Outputs  
140ms Reset Timeout Period—No External  
A 3-pin SOT23 package allows for a significant reduc-  
tion in board space and improves reliability compared  
to multiple-IC/discrete solutions. These devices have a  
minimum order increment of 2,ꢀ00 pieces.
