Overview
The LM217LD13TR is a low-current, positive adjustable linear voltage regulator manufactured by STMicroelectronics. It operates within an input voltage range of 4.2 V to 40 V and provides an adjustable output voltage from 1.2 V to 37 V. The device delivers a maximum output current of 100 mA with line regulation of 0.04 %/V and load regulation of 0.5 %. It features a typical power supply rejection ratio (PSRR) of 80 dB and functions reliably across an operating temperature range of 0°C to +125°C. The component is housed in an SOIC-8 surface-mount package.
Feature Summary
- Provides stable positive adjustable voltage regulation using only a resistive divider network for configuration.
- Includes comprehensive protection mechanisms against thermal overload and short-circuit conditions.
Applications
- General-purpose positive adjustable voltage regulation
- Local card-level regulation in embedded systems
- Pre-regulator stages for switching regulators
Procurement Notes
Verify the specific suffix LD13TR corresponds to the SOIC-8 tape-and-reel packaging format required for your assembly process. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations prior to final procurement decisions.
Selection Notes
Select this component when a low-current solution up to 100 mA is sufficient for the application load requirements. Ensure the design accommodates the minimum input-to-output differential voltage necessary for proper regulation. Consider the SOIC-8 package dimensions and thermal dissipation capabilities relative to the expected ambient operating conditions.
Part Context
This part belongs to the LM217L series of monolithic integrated circuits designed as positive adjustable voltage regulators. It shares functional similarities with the LM317L but is specifically rated for lower current applications. The series eliminates the need for stocking multiple fixed-voltage regulators by allowing flexible output voltage selection via external resistors.
Replacement Considerations
LM317LD13TR: Pin-compatible alternative with identical electrical characteristics and packaging, suitable for direct substitution in existing designs requiring equivalent performance specifications.
