Overview
The LM117HVH/NOPB is a high-voltage three-terminal adjustable linear regulator manufactured by Texas Instruments. It provides an output current of 1.5 A with an adjustable output voltage range from 1.25 V to 60 V. The device operates within a temperature range of 0°C to +125°C and features a line regulation of 0.04%/V and load regulation of 0.5%. It utilizes a TO-39-3 through-hole package and includes internal protections such as thermal shutdown and current limiting.
Feature Summary
- Capable of delivering 1.5 A output current across a wide input voltage range up to 60 V
- Provides precise adjustable output voltage control using only two external resistors
- Includes comprehensive protection mechanisms against thermal overload and excessive current
Applications
- High-voltage power supply systems requiring adjustable regulation
- Industrial equipment power management circuits
- Test and measurement instrument power stages
Procurement Notes
Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence when sourcing. Confirm the TO-39-3 package type matches your board layout requirements. Ensure the supplier provides valid datasheets for the LM117HVH series to validate electrical characteristics against your design specifications before finalizing procurement.
Selection Notes
Select this component when high input voltage tolerance exceeding standard regulators is required. The adjustable output feature offers flexibility for varying load requirements without changing hardware. Consider the thermal performance in the TO-39 package for heat dissipation needs in enclosed environments compared to surface-mount alternatives.
Part Context
This part belongs to the LM117HV family of high-voltage adjustable regulators from Texas Instruments. It serves as a robust solution for applications demanding higher voltage handling capabilities than standard low-voltage regulators. The NOPB suffix denotes a lead-free, halogen-free version compliant with environmental standards.
Replacement Considerations
LM117HVHRQMLV is a space-grade alternative offering similar high-voltage adjustable regulation capabilities.
