Note 1:
MAX6129 is 100% production tested at TA = +25°C and is guaranteed by design for TA = TMIN to TMAX as specified.
Note 2:
Temperature coefficient is defined by box method: (VMAX - VMIN)/(∆T ✕ V+25°C).
Note 3:
Not production tested. Guaranteed by design for both SOT23 and dice.
Note 4:
Only the typical values apply to MAX6129A sold in die form (max values apply to packaged parts).
Note 5:
Thermal hysteresis is defined as the change in output voltage at TA = +25°C before and after cycling the device from TMAX to TMIN.
Note 6:
Dropout voltage is the minimum input voltage at which VOUT changes by 0.1% from VOUT at rated VIN and is guaranteed by Load Regulation Test.
