Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the manufacturer designation on the component marking, as this part number is primarily associated with Texas Instruments. Confirm the specific suffix requirements for packaging and RoHS compliance with the authorized distributor. Ensure the supplier provides valid traceability documentation matching the requested specifications before finalizing the purchase order.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a low-current (100mA) adjustable linear regulator is required in a compact surface-mount form factor. It serves as a suitable alternative to higher-current variants like the standard LM317 when space constraints or lower power dissipation are primary design considerations. Verify that the input-to-output differential voltage remains within safe limits to manage thermal performance effectively.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the LM317 family of adjustable voltage regulators, known for their versatility and robustness in analog power supply designs. While the standard LM317 supports up to 1.5A, the 'L' variant specifically targets applications requiring reduced current capacity and smaller physical footprints, making it ideal for portable electronics and dense PCB layouts.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes include the LM317LIPKG3 and LM317LCPK from Texas Instruments, which share identical electrical characteristics and pinouts. Other manufacturers may offer equivalent parts such as the NCV317L series, but verification of pin compatibility and thermal resistance parameters is essential.
