Overview
The LM217LZ-AP is a linear voltage regulator manufactured by STMicroelectronics, belonging to the LM217L series. It functions as an adjustable positive standard regulator with an output voltage range of 1.2 V to 37 V. The device supports an output current of 0.2 A and utilizes a PDSO8 package for surface-mount installation. Key electrical parameters include a line regulation of 0.02 %/V and a load regulation of 0.3 %. It operates within a temperature range of -40°C to +125°C and features a typical PSRR of 80 dB.
Feature Summary
- Provides stable adjustable positive voltage regulation across a wide input range
- Integrates comprehensive protection mechanisms including thermal shutdown and short-circuit limiting
- Designed for floating operation suitable for high-voltage applications
Applications
- General-purpose linear power supply circuits
- Local voltage regulation for embedded systems
- Battery-powered equipment requiring stable DC output
Procurement Notes
Verify the specific suffix 'AP' against official STMicroelectronics documentation to confirm exact marking and tape-and-reel specifications. Ensure compatibility with the required PDSO8 footprint and verify that the 0.2 A current rating meets system demands. Cross-reference the datasheet revision date to ensure alignment with current manufacturing standards and RoHS compliance requirements.
Selection Notes
Select this component when a low-cost, adjustable positive regulator is needed for moderate current loads up to 0.2 A. It is suitable for designs prioritizing simplicity over high-efficiency switching, particularly where noise sensitivity is managed by the inherent characteristics of linear regulation. Consider the thermal dissipation capabilities of the PDSO8 package under maximum load conditions.
Part Context
The LM217L series represents a family of adjustable positive voltage regulators from STMicroelectronics. Variants such as LM217L_05 and LM217L_07 share similar electrical characteristics but differ in packaging options like TO-92 or SOIC. This series serves as a cost-effective alternative to fixed regulators, offering flexibility in setting output voltages via external resistors while maintaining robust protection features.
Replacement Considerations
LM217L_07: Similar adjustable regulator in PDSO8 package with comparable electrical performance. LM217L_05: Alternative variant available in different packaging configurations. Verify pinout compatibility and thermal characteristics before substitution.
