LM2830XMF Equivalent & Substitute Parts Reference
Part Overview
The LM2830XMF, manufactured by Texas Instruments, is categorized under Power Management (PMIC) components. It is an adjustable positive buck switching regulator IC with a maximum output of 1A, housed in the SC-74A, SOT-753 package. With a minimum input voltage of 3V and a maximum of 5.5V, its output voltage is adjustable from 0.6V to 4.5V. The device operates at a switching frequency of 1.6MHz, does not feature a synchronous rectifier, and is rated for an operating temperature range of -40°C to 125°C. The product is obsolete, requiring evaluation of alternative or substitute models that meet identical electrical and mechanical specifications for ongoing design or maintenance needs.

The LM2830XMF/NOPB directly matches all listed electrical, mechanical, and compliance parameters, including RoHS and REACH certifications, operating temperature, package specifications, and mounting type. LM2830XMF/NOPB is active and fulfills moisture sensitivity level requirements, ensuring uninterrupted compliance for regulated markets.
Frequently Asked Questions (FAQ)
Q1: Which parameters must match for substituting a buck switching regulator IC?
A1: Substitution requires exact matching of manufacturer, operating voltage ranges, output current, topology, function, package type, output configuration, output type, switching frequency, operating temperature, RoHS status, REACH status, and MSL.
Q2: Does the LM2830XMF/NOPB offer compatibility in PCB layout?
A2: Both LM2830XMF and LM2830XMF/NOPB use the SC-74A, SOT-753 package and SOT-23-5 supplier device package, ensuring mechanical and pin compatibility.
Q3: Are RoHS or REACH differences relevant for these PMIC substitute parts?
A3: No differences; both LM2830XMF and LM2830XMF/NOPB are ROHS3 compliant and REACH unaffected, meeting standard environmental regulations.
Q4: Is there a difference in moisture sensitivity between LM2830XMF and LM2830XMF/NOPB?
A4: No; both devices are rated at Moisture Sensitivity Level (MSL) 1 (Unlimited).
Q5: Can the substitute part be used across the same operating temperature range?
A5: Yes; both parts support -40°C ~ 125°C (TJ).
Q6: How is product status relevant to selection?
A6: LM2830XMF is obsolete. LM2830XMF/NOPB is active and meets all listed selection criteria.
