MAX6330SUR-T

Overview

The MAX6330SUR-T is a precision shunt regulator with an integrated power-on reset function housed in a SOT23-3 package. It provides a regulated shunt voltage of 3.0V with ±1.5% tolerance and operates within a shunt current range of 100µA to 50mA. The device features an active-low push/pull reset output with a 140ms timeout period, ensuring protection against power-up, power-down, and brownout conditions. Operating temperature range is -40°C to +85°C.

Feature Summary

Combines a precision shunt regulator with a microprocessor supervisory circuit in a single compact package
Provides active-low push/pull reset output for reliable system initialization during power events
Offers high transient immunity and stable regulation across a wide shunt current range

Applications

Microprocessor-based controllers
Household appliances
Intelligent instruments
Critical microcontroller power monitoring
Portable or size-sensitive equipment

Procurement Notes

Verify the specific suffix 'S' indicates the 3.0V shunt voltage option when ordering. Confirm lead-free packaging status by checking for the '+T' designation versus '-T'. Ensure minimum order increments are met as specified by the manufacturer. Validate that the active-low reset polarity matches the target microprocessor requirements before finalizing procurement.

Selection Notes

Select this component when board space is limited and both voltage regulation and reset supervision are required. The SOT23-3 package offers significant space reduction compared to discrete solutions. Consider the 3.0V output level and active-low reset logic compatibility with the target system architecture. Evaluate thermal derating requirements if operating at maximum shunt currents in elevated ambient temperatures.

Part Context

This part belongs to the MAX6330/MAX6331 family of precision shunt regulators with reset functions. The MAX6330 variant specifically provides an active-low reset output, whereas the MAX6331 provides an active-high output. Both share identical shunt regulator characteristics but differ in reset output polarity to accommodate various microprocessor interface standards.
