MAX6330：Precision Shunt Regulators with Reset in SOT23-3

Industry's Only Shunt Regulator + Reset in SOT Package

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 protecting µPs from power-up, power-down, and brownout conditions. 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. A 3-pin SOT23 package allows for a significant reduction in board space and improves reliability compared to multiple-IC/discrete solutions. These devices have a minimum order increment of 2,500 pieces.
