MAX6190–MAX6195/MAX6198Precision, Micropower, Low-Dropout Voltage ReferencesELECTRICAL CHARACTERISTICS—MAX6198 (VIN = 5V, IOUT = 0nA, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

Note 2: Thermal Hysteresis is defined as the change in +25°C output voltage before and after cycling the device from TMIN to TMAX. Note 3: Not production tested. Guaranteed by design. Note 4: Dropout voltage is the minimum input voltage at which VOUT changes ≤ 0.2% from VOUT at VIN = 5.0V (VIN = 5.5V for MAX6195). 8 Maxim Integrated
