| FFF Compatibility | The alternative uses the identical SOT-23-3 package with the exact same pinout configuration: Pin 1 (IN), Pin 2 (OUT), and Pin 3 (GND).The physical dimensions and surface mount footprint are fully compatible with standard SOT-23-3 (TO-236-3) landing patterns.The alternative meets or exceeds all electrical parameters, including matching output voltage (1.25 V), high accuracy (±0.15%), and temperature stability (30 ppm/°C), while offering a better current drive capacity and lower quiescent power. | The alternative uses the identical SOT-23-3 package with the exact same pinout configuration: Pin 1 (IN), Pin 2 (OUT), and Pin 3 (GND).The physical dimensions and surface mount footprint are fully compatible with standard SOT-23-3 (TO-236-3) landing patterns.While the part delivers the correct 1.25 V output, it has a slightly relaxed initial accuracy tolerance (±0.2% vs ±0.15%), higher temperature drift (75 ppm/°C vs 30 ppm/°C), and higher typical supply current (50 µA vs 10 µA). | ||
 AI Summary | TS3312AMR by STMicroelectronics: Series Voltage Reference IC Fixed 1.25V V ±0.15% 5 mA SOT-23-3. | The Texas Instruments REF3312AIDBZR is a highly precise series voltage reference that serves as an outstanding drop-in replacement. It perfectly matches the output voltage, precision tolerance, thermal drift, and package/pinout of the TS3312AMR, while reducing quiescent current and offering a higher output drive capability. This is the highest-confidence second-source option.
| The Texas Instruments REF3012AIDBZR is a widely available, low-power, drop-in series reference in SOT-23-3. While it shares the exact pinout and matches physical features, it is a budget-friendly option with slightly wider tolerance and higher drift compared to the high-precision TS3312AMR. This is a solid alternative if extreme temperature stability is not a critical system requirement.
