Ultra-Low-Power Series Voltage ReferenceMAX6129ELECTRICAL CHARACTERISTICS—MAX6129_50 (VOUT = 5.000V) (VIN = 5.2V, IOUT = 0, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

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. _______________________________________________________________________________________7
