| FFF Compatibility | The package (10-WSON 3x3) and pinout configuration are identical, making this a direct drop-in replacement.Both parts share the same physical dimensions (3.00 mm x 3.00 mm) and package outline (WSON-10).Features the same ultra-low noise architecture with higher output current (2A vs 1A) and identical output voltage range. | The pinout is completely different from the TPS7A9401, requiring a board redesign.Both parts use a 10-pin 3.00 mm x 3.00 mm package footprint (DFN vs WSON).Output current capability is reduced to 500mA (vs 1A), and it has higher output noise (0.8 µVRMS vs 0.46 µVRMS). | ||
 AI Summary | TPS7A9401DSCR by Texas Instruments: Linear Voltage Regulator IC Positive Adjustable 1 Output 1A 10-WSON (3x3). | The TPS7A9601DSCR is a high-current, pin-compatible upgrade to the TPS7A9401DSCR, increasing the output current capability to 2A while maintaining the industry-leading ultra-low noise and PSRR specifications. It is a seamless drop-in replacement for designs needing a robust second-source option or higher current headroom.
| The LT3045 is an alternative from Analog Devices that matches the physical footprint size (3x3 DFN-10) but utilizes a different pinout. It is limited to 500mA of output current, making it suitable for lower-power sub-circuits or where the PCB layout can be updated to accept the Analog Devices ultra-low noise LDO architecture.
