Overview
The SPX431LAM-L is a three-terminal adjustable shunt voltage regulator manufactured by Sipex. It provides a highly accurate bandgap reference with an output voltage range of 2.495 V to 20 V, set via two external resistors. The device operates as an open-loop error amplifier and functions as a two-terminal voltage reference. It supports a maximum shunt current of 100 mA and maintains an initial accuracy of 0.5% with a temperature coefficient of 30 PPM/°C. The component operates within a temperature range of 0°C to +105°C and is housed in a SOT-89-3 package.
Feature Summary
- Provides a highly accurate bandgap reference for precision applications
- Functions as an open-loop error amplifier with adjustable output
- Supports wide input voltage ranges up to 20 V
Applications
- Precision voltage regulation circuits
- Open-loop error amplifier implementations
- Adjustable power supply references
Procurement Notes
Verify the manufacturer status carefully, as the SPX431L series has undergone corporate transitions involving MaxLinear and legacy Sipex branding. Confirm the specific lot date code and RoHS compliance details against the latest official datasheet, as availability varies significantly across distributors. Ensure the package type matches the required SOT-89-3 footprint for your design.
Selection Notes
Select this component when a low-cost, adjustable shunt reference is required for moderate current applications. It is suitable for designs needing a stable reference voltage between 2.495 V and 20 V. Consider the 30 PPM/°C temperature coefficient for thermal stability requirements. Verify that the 100 mA maximum shunt current meets the load demands of the target circuit.
Part Context
The SPX431LAM-L belongs to the SPX431L family of adjustable shunt regulators. This series is widely used in power management ICs for providing stable reference voltages. The 'LAM' suffix typically denotes specific packaging or testing variations within the Sipex product line, distinct from other variants like the SPX431LM.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official cross-reference guides from MaxLinear or Sipex for verified equivalents.
