Overview
The LM217LZ is a monolithic integrated circuit manufactured by STMicroelectronics, designed as a positive adjustable voltage regulator. It is housed in a TO-92-3 through-hole package and supports an output voltage range of 1.2 V to 37 V. The device provides up to 100 mA of load current. Key electrical specifications include a line regulation of 0.02 %/V, load regulation of 0.3 %, and a typical PSRR of 80 dB. It operates within a temperature range of -25 °C to +125 °C.
Feature Summary
- Adjustable output voltage selection via external resistive divider
- Integrated thermal overload protection for safety
- Short-circuit protection capabilities
- Floating operation suitable for high-voltage applications
Applications
- General-purpose positive adjustable voltage regulation
- Local card regulation in distributed power systems
- Programmable output power supplies
Procurement Notes
Verify the specific suffix 'Z' against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure the ordering part number matches the required lead-free or RoHS compliance status defined in the latest product documentation. Cross-reference the manufacturer code with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a low-cost, adjustable linear regulator is required for currents up to 100 mA. The TO-92 package is suitable for low-power through-hole designs. Consider higher current variants like the LM217T if loads exceed 100 mA. Verify that the input-to-output differential voltage remains within safe operating limits to prevent excessive power dissipation.
Part Context
The LM217L belongs to the LM217 family of adjustable regulators from STMicroelectronics. This family includes variants with different packages such as SO-8 and TO-92. The LM217L series is distinct from the higher-current LM217/LM317 series, which supports over 1.5 A. The LM217L is specifically optimized for lower current applications requiring compact packaging.
