| FFF Compatibility | The VSON-8 (DRB) package requires a different footprint / land pattern on the PCB compared to the HVSSOP-8 (DGN) package.The VSON-8 is a leadless plastic small-outline package with smaller overall physical dimensions (3.00 mm x 3.00 mm vs MSOP-8 body length) and a different vertical profile.The electrical specifications, including input range, output voltage range, current capability, PSRR, and noise characteristics, are exactly identical. | Pin 6 is a No Connection (NC) instead of Noise Reduction (NR/SS), and Pin 7 is an NC instead of Do Not Connect (DNC). While the baseline functions (IN, OUT, FB, EN, GND) match exactly, any external soft-start capacitor on Pin 6 will be left floating.It uses the identical 8-HVSSOP (DGN) package and mechanical dimensions.It has a much lower maximum output current of 50mA compared to the original 150mA, and lacks the noise-reduction/soft-start pin functionality. | ||
 AI Summary | TPS7A4901DGNT by Texas Instruments: Linear Voltage Regulator IC Positive Adjustable 1 Output 150mA 8-HVSSOP. | This is the direct same-die sibling from the same Texas Instruments family, offered in a leadless VSON-8 package instead of the HVSSOP-8 package. It provides identical electrical specs, making it the most reliable functional second-source option if a PCB footprint redesign can be accommodated.
| This is a same-package sibling within TI's high-voltage LDO family. It can be mounted on the exact same footprint, but it is limited to 50mA maximum output current and lacks the noise-reduction/soft-start pin connection.
