SPX432AM-L

Overview

The SPX432AM-L is a three-terminal adjustable shunt voltage regulator manufactured by MaxLinear. It provides a highly accurate 1.24V bandgap reference with a tolerance of ±0.5%. The device supports an output voltage range from 1.24V to 18V and delivers a maximum sink current of 80mA. It features a temperature coefficient of 50ppm/°C and operates within a junction temperature range of 0°C to 105°C. The component is housed in a SOT-23-3 surface-mount package.

Feature Summary

Provides a precise 1.24V bandgap reference voltage source
Supports wide programmable output voltage adjustment via external resistors
Delivers high sink current capacity for driving series pass transistors
Maintains thermal stability across extended industrial temperature ranges

Applications

Precision high-current series regulators
Programmable power supplies
Battery chargers
Voltage references for analog circuits

Procurement Notes

Verify the obsolete status of this part number before procurement planning, as indicated by distributor records. Confirm that the SOT-23-3 package dimensions align with existing PCB footprints. Ensure design-in compatibility with the specific 1.24V reference requirement and 80mA current capability. Validate that the ±0.5% initial accuracy meets system specifications without requiring additional calibration steps.

Selection Notes

Select this component when a stable, low-noise reference is required for adjustable shunt regulation applications. The 80mA current rating allows direct drive of external pass transistors for higher current outputs. The SOT-23-3 package offers space efficiency for compact designs. Consider the 50ppm/°C temperature coefficient for thermal drift requirements in precision measurement or control systems.

Part Context

The SPX432AM-L belongs to the SPX432 family of precision shunt regulators. This family is designed to provide accurate voltage references for various power management and signal conditioning applications. The device utilizes bandgap technology to ensure consistent performance over temperature variations, making it suitable for industrial and commercial electronics requiring reliable voltage regulation.
