Typical values are at TA = +25°C.) (Note 1) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specificatio ns is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

MAX6012/6021/6025/6030/6041/6045/6050 Precision, Low-Power, Low-Dropout, SOT23-3 Voltage References Note 1: All devices are 100% production tested at TA = +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified. Note 2: Temperature Coefficient is measured by the “box” method, i.e., the maximum ∆VOUT is divided by the maximum ∆t. Note 3: Temperature Hysteresis is defined as the change in +25°C output voltage before and after cycling the device from TMIN to TMAX. Note 4: Not production tested. Guaranteed by design. Note 5: Dropout voltage is the minimum input voltage at which VOUT changes ≤0.2% from VOUT at VIN = 5.0V (VIN = 5.5V for MAX6050).

The extremes of these characteristics are found in the MAX6012 (1.2V output) and the MAX6050 (5.0V output). The Typical Operating Characteristics of the remainder of the MAX6012 family typically lie between these two extremes and can be estimated based on their output voltage.

TRANSISTOR COUNT: 70 Turn-On Time These devices typically turn on and settle to within 0.1% of their final value; 30µs to 220µs depending on the device. The turn-on time can increase up to 1.5ms with the device operating at the minimum dropout volt- age and the maximum load. Positive and Negative Low-Power Voltage Reference Figure 1 shows a typical method for developing a bipo- lar reference. The circuit uses a MAX681 voltage dou- bler/inverter charge-pump converter to power an ICL7652, thus creating a positive as well as a negative reference voltage.
