Overview
The LM1084IS-12/NOPB is a fixed-output positive low dropout regulator manufactured by Texas Instruments. It provides a stable 12V output with a maximum load current of 5A. The device features a maximum voltage dropout of 1.5V at full load and supports an input voltage up to 18V. Packaged in a TO-263 (D2PAK) surface-mount housing, it operates within a temperature range of -40°C to 125°C. Internal protections include overcurrent limiting and thermal shutdown.
Feature Summary
- Fixed 12V output configuration for simplified circuit design
- High current capability supporting up to 5A continuous load
- Low dropout performance ensuring efficiency under varying conditions
- Integrated thermal and current protection mechanisms
Applications
- General purpose power supply regulation
- Battery charging circuits
- Post-regulation for switching supplies
- Interface power distribution
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free packaging compliant with RoHS standards. Confirm the package designation matches the required PCB footprint, as variations exist between standard and tape-and-reel formats. Ensure the input voltage does not exceed the 18V absolute maximum rating during operation to prevent device damage.
Selection Notes
Select this component when a fixed 12V rail is required with high current capacity. It serves as a direct pin-compatible replacement for industry-standard LM317 devices where fixed output is preferred. Consider the thermal dissipation requirements given the 5A capability and potential power loss across the dropout voltage.
Part Context
This part belongs to the LM1084 series of low dropout regulators from Texas Instruments. The series includes adjustable variants and other fixed voltage options. The ISX or IS prefix denotes the surface-mount TO-263 package type, distinguishing it from through-hole alternatives while maintaining identical electrical characteristics.
