MAX6331
Precision Shunt Regulators with Reset in SOT23-3
Industry's Only Shunt Regulator + Reset in SOT Package
Overview
- 100µA to 50mA Shunt Current Range
- Low Cost
- 3-Pin SOT23 Package
- ±1.5% Tolerance on Output Voltage
- Three Shunt Voltages Available: 5V, 3.3V, 3.0V
- Precision Power-On Reset Threshold:
- 1.5% Tolerance Available with Either
- RESET (MAX6331) or active-low RESET (MAX6330) Outputs
- 140ms Reset Timeout Period-No External Components Required
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.
