The MAX6133A30+ ships in a Tube, housed in an 8-TSSOP or 8-MSOP (0.118", 3.00mm Width) package. The 0.118" width fits a standard 3.00 mm pad layout.
Precision specs — what the tolerance and drift mean for your rail
±0.06% initial accuracy on the 3V fixed output means the reference is within 1.8 mV of 3.000 V at 25°C — tight enough for a 12-bit ADC without external trimming.
Output current and supply current — the power budget trade-off
The series reference delivers up to 15 mA output while drawing only 85 µA quiescent supply current — the load regulation is dominated by the internal pass transistor's Rds(on), not the bias current. Input voltage range is 3.2 V to 12.6 V — the 200 mV headroom above the 3 V output is the dropout voltage at no load; at 15 mA the dropout rises to about 400 mV, so the input rail must stay above 3.4 V across the full load and temperature range.
