Note 2: Not production tested. Guaranteed by design. Note 3: Dropout voltage is the minimum input voltage at which VOUT changes ≤ 0.2% from VOUT at rated VIN and is guaranteed by Load Regulation Test. Note 4: Thermal hysteresis is defined as the change in TA = +25°C output voltage before and after temperature cycling of the device (from TA = TMIN to TMAX). Initial measurement at TA = +25°C is followed by temperature cycling the device to TA = +85°C then to TA = -40°C and another measurement at TA = +25°C is compared to the original measurement at TA = +25°C.

Precision, Micropower, 1.8V Supply, Low-Dropout, SOT23 Voltage Reference Detailed Description The MAX6018 is a precision, low-voltage, low-dropout, micropower, bandgap voltage reference in a SOT23 package. This three-terminal reference operates with an input voltage from (V OUT + 200mV) to 5.5V, and is available with output voltage options of 1.2V, 1.6V, 1.8V, and 2.048V. These devices can source up to 1mA with <200mV of dropout voltage, making them attrac- tive for use in low-voltage applications. Applications Information Output/Load Capacitance These devices require a minimum of 100pF load to maintain output stability. They remain stable for capacitive loads as high as 1µF. In applications where the load or the supply can experi- ence step changes, a larger output capacitor reduces the amount of overshoot (or undershoot) and assists the circuit’s transient response. Otherwise, applications may not need more than 100pF. Supply Current The 5µA maximum supply current varies only 0.1µA/V with the supply voltage. When the supply voltage is below the minimum-speci- fied input voltage (as during turn-on), the devices can draw up to 20µA beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on. Turn-On Time These devices typically turn on and settle to within 0.1% of their final value in 200µs. The turn-on time can increase up to 1ms with the device operating at the minimum dropout voltage and the maximum load.
