Overview
The LM217LZ-TR is a positive adjustable linear voltage regulator manufactured by STMicroelectronics. It operates within an output voltage range of 1.2 V to 37 V and supports a maximum output current of 1.5 A. The device features a line regulation of 0.02 %/V and load regulation of 0.3 %. Typical power supply rejection ratio (PSRR) is 80 dB. It functions in through-hole TO-92-3 packages with operating temperatures from -25 °C to +125 °C.
Feature Summary
- Provides adjustable positive voltage regulation across a wide input range
- Integrates internal current limiting, thermal shutdown, and safe operating area protection
- Enables floating operation for high-voltage applications
Applications
- General-purpose power supply circuits requiring adjustable output
- Local card-level regulation systems
- High-voltage floating operational environments
Procurement Notes
Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the thermal management requirements align with the TO-92-3 package limitations under expected load conditions. Ensure compatibility with the intended input voltage range and adjust resistor values for the desired output voltage setting.
Selection Notes
Select this component when a low-cost, adjustable positive regulator is needed for currents up to 1.5 A. The TO-92-3 package suits through-hole assembly processes. Consider thermal dissipation capabilities relative to the ambient temperature and load current. Verify that the line and load regulation specifications meet the precision requirements of the target application circuit.
Part Context
This part belongs to the LM217L series of monolithic integrated circuits designed as positive adjustable voltage regulators. It shares functional similarities with other members of the family but differs in packaging and current handling capabilities compared to higher-current variants like the LM217T or LM217M.
Replacement Considerations
LM217LZ is a non-trailing equivalent variant. Cross-reference pinouts and electrical characteristics carefully. Other manufacturers produce functionally similar adjustable regulators, but direct substitution requires verification of package dimensions and thermal performance.
