Functionally similar 1A adjustable LDO, but requires board redesign and is only suitable for low input voltage applications (<5.5V).
TLV76701DRVR is a 1A adjustable LDO in a WSON-6 package, suitable for applications needing a wide input voltage range up to 16V. Finding a direct drop-in replacement is challenging due to unique pinouts and parametric combinations.
WSON-6 package is common, but pinout is the issue.
Alternatives have significant differences in input voltage or output current.
LDOs are analog components and typically do not require firmware changes.
No direct drop-in replacement for TLV76701DRVR is available among the reviewed parts.
For applications with Vin < 5.5V, consider TPS7A3701DRVR after a board redesign. Otherwise, a new component search is needed for a 1A, high-voltage LDO.
Pinout mismatch is the primary barrier, forcing a board redesign for any alternative.

| Feature / factor | TLV76701DRVR | TPS7A3701DRVR | TPS7A2601DRVR | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | WSON-6 | WSON-6 | WSON-6 | WSON-6 — Package is physically compatible.; TPS7A2601DRVR: Package is physically compatible. | |
| Pinout | See datasheet | Different | Different | Different — Pin functions differ (e.g., pin 4 is NR/SS vs FB). Requires board redesign.; TPS7A2601DRVR: Pin functions differ (e.g., pin 4 is PG). Requires board redesign. | |
| Current | 1 A | 1 A | 500 mA | 1 A / 500 mA — Output current capability matches.; TPS7A2601DRVR: Output current is 50% lower than target. | |
| Voltage | 2.5 V to 16 V | 2.2 V to 5.5 V | 2.4 V to 18 V | 2.2 V to 5.5 V / 2.4 V to 18 V — Max input voltage is significantly lower.; TPS7A2601DRVR: Input voltage range is comparable and slightly wider. | |
| Function | Adjustable | Adjustable | Adjustable | Adjustable — Both are adjustable LDOs, but Vout ranges differ.; TPS7A2601DRVR: Both are adjustable LDOs. |
There are no direct pin-compatible replacements. TPS7A3701DRVR offers the same 1A current but has a lower input voltage range (max 5.5V) and requires a board redesign. Other functional alternatives may involve a reduction in output current.
