MAX6330/MAX6331  
Precision Shunt Regulators with  
Reset in SOT23-3  
General Description  
Features  
100µA to 50mA Shunt Current Range  
The MAX6330/MAX6331 combine a precision shunt regu-  
lator 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 protecting µPs from power-  
up, power-down, and brownout conditions.  
Low Cost  
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  
50mA, 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  
Components Required  
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 2,500 pieces.
