Procurement Notes
Verify availability status as the component may be discontinued or subject to limited supply. Confirm RoHS compliance and REACH SVHC details with the manufacturer before procurement. Ensure the specific suffix matches design requirements. Check for obsolescence notifications or product discontinuance announcements from onsemi prior to finalizing orders.
Selection Notes
Select this regulator when a fixed 5 V output at 150 mA is required in through-hole designs. Consider thermal management capabilities given the operating temperature limits. Verify input voltage headroom to ensure proper dropout performance. Compare against similar L78 series variants if higher current or different packaging is needed.
Part Context
This part belongs to the L78LR family of low-dropout linear regulators produced by onsemi. These components are widely used in general-purpose power management circuits requiring reliable voltage stabilization. The L78LR series offers compatibility with standard TO-92 packages, facilitating easy replacement in legacy designs.
Replacement Considerations
Compatible substitutes include L78LR05, L78LR05D, L78M05FA, L78LR50MA, L78MR05, and L78MR05FA. Verify pinout and electrical specifications match before substitution.
