Overview
The LM120H-5.0 is a Texas Instruments linear voltage regulator IC providing a fixed negative output of -5.0V. It supports an output current of up to 1.5A and operates with a maximum input voltage of -25.0V. The device features a dropout voltage of approximately 3.00V and maintains a quiescent current of 2mA. It is housed in a TO-3 package, suitable for through-hole mounting, and functions within an extended temperature range of -55°C to +150°C.
Feature Summary
- Provides a stable fixed negative voltage output
- Capable of delivering high output current up to 1.5A
- Designed for operation across extended industrial temperature ranges
Applications
- Negative power supply rails in electronic circuits
- Industrial control systems requiring robust voltage regulation
- Military-grade applications utilizing the -883 variant
Procurement Notes
Verify the specific suffix (e.g., /NOPB, /883) to ensure compliance with RoHS standards and military specifications. Confirm package type and lead configuration match the design requirements. Check datasheet revisions for any updates on electrical characteristics or recommended operating conditions before finalizing procurement.
Selection Notes
Select this component when a fixed negative voltage is required with high current capability. Ensure the input voltage does not exceed the maximum rating of -25.0V. Consider the thermal management needs due to the TO-3 package and potential power dissipation at higher load currents. Verify compatibility with ceramic output capacitors as specified.
Part Context
This part belongs to the LM120 series of three-terminal negative regulators from Texas Instruments. It is designed for general-purpose linear regulation applications where a reliable negative voltage source is needed. The series includes various output voltage options and packages to suit different system requirements.
Replacement Considerations
The LM120H-5.0/NOPB is a direct replacement offering RoHS compliance. For military specifications, the LM120H-5.0/883 variant is available. Ensure pinout and thermal characteristics are compatible when substituting.
