LM3208TL/NOPB Equivalent & Substitute Parts
Part Overview
The LM3208TL/NOPB is a Converter, RF Power Amplifier Voltage Regulator IC manufactured by Texas Instruments, designed for single-output power management applications in RF power amplifier circuits. This device operates with input voltage range of 2.7V to 5.5V and provides adjustable output voltage from 0.8V to 3.6V. The part is classified as Obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation
Substitution of the LM3208TL/NOPB is determined by the following critical parameters:
- Input voltage compatibility: Substitute must accept 2.7V to 5.5V input range
- Output voltage capability: Substitute must support adjustable output voltage within or overlapping the 0.8V to 3.6V range
- Single output configuration: Substitute must provide exactly one output
- Surface mount technology: Substitute must use surface mount packaging
- Regulatory compliance: Substitute must maintain ROHS3 compliance and equivalent environmental certifications
The TPS62801YKAR meets these substitution criteria as an Active product with overlapping electrical specifications and equivalent compliance status.

Engineering Selection Recommendations
The TPS62801YKAR is an Active product substitute for the obsolete LM3208TL/NOPB. Both devices maintain ROHS3 compliance and equivalent environmental certifications (REACH Unaffected, EAR99 ECCN classification). The substitute provides extended operating temperature range (-40°C to 125°C versus -30°C to 85°C) and maintains input voltage maximum compatibility at 5.5V.
Design consideration: The TPS62801YKAR has a maximum output voltage of 1.55V, which is lower than the LM3208TL/NOPB maximum of 3.6V. Applications requiring output voltages above 1.55V are not compatible with this substitute and require alternative component selection.
Frequently Asked Questions (FAQ)
Q: Why is the LM3208TL/NOPB classified as Obsolete? A: The LM3208TL/NOPB has reached end-of-life status with Texas Instruments. Substitute components must be identified for new designs and production continuity.
Q: Can the TPS62801YKAR directly replace the LM3208TL/NOPB in all applications? A: No. The TPS62801YKAR has a maximum output voltage of 1.55V, while the LM3208TL/NOPB supports up to 3.6V. Applications requiring higher output voltages require alternative substitutes.
Q: What are the key electrical parameters that determine substitution compatibility? A: Input voltage range (2.7V to 5.5V minimum), output voltage capability (0.8V minimum), single output configuration, and surface mount packaging are the primary substitution criteria.
Q: Are both devices RoHS compliant? A: Yes. Both the LM3208TL/NOPB and TPS62801YKAR are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
Q: What is the package difference between these devices? A: The LM3208TL/NOPB uses 8-WFBGA packaging, while the TPS62801YKAR uses 6-XFBGA, DSBGA packaging. PCB layout and footprint modifications are required for substitution.
Q: Does the TPS62801YKAR support the same input voltage range? A: The TPS62801YKAR accepts 1.8V to 5.5V input, which overlaps the LM3208TL/NOPB range of 2.7V to 5.5V. The substitute supports lower minimum input voltage.
