Overview
The LM1085ISX-5.0/NOPB is a Texas Instruments low-dropout positive linear regulator providing a fixed 5 V output with a maximum load current of 5 A. It operates within an input voltage range of 2.6 V to 25 V and features a typical dropout voltage of 1.3 V, reaching a maximum of 1.5 V at full load. The device maintains a quiescent current of 5 mA and offers high power dissipation capability up to 30 W. It is housed in a surface-mount D2PAK-3 (TO-263-3) package and supports operation from -40 °C to +125 °C.
Feature Summary
- Provides stable fixed 5 V regulation for high-current applications up to 5 A
- Ensures efficient power conversion with low dropout voltage characteristics
- Delivers robust thermal performance with high power dissipation capacity
Applications
- Point-of-load regulation in distributed power architectures
- Pre-regulation stages for switching converters
- Battery-powered systems requiring efficient linear regulation
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the 'S' and 'X' designators correspond to the correct TO-263-3 surface mount package variant. Ensure the fixed 5.0 V output rating matches the target circuit requirements before procurement.
Selection Notes
Select this component when a fixed 5 V rail is required with significant current demand exceeding standard LDO capabilities. The wide input voltage range accommodates varying supply conditions. Consider the thermal resistance of the D2PAK package and ensure adequate PCB copper area or heatsinking is available to manage the 30 W power dissipation potential under heavy loads.
Part Context
This part belongs to the LM1085 family of adjustable and fixed output regulators known for high current handling. The ISX designation indicates a surface-mount version in the TO-263 package. It serves as a robust solution for mid-power linear regulation tasks where efficiency and thermal management are critical design factors.
Replacement Considerations
LM1085IS-5.0/NOPB is the non-tape-and-reel equivalent. LM1084ISX-5.0/NOPB offers similar functionality but with different thermal and current specifications.
