ELECTRICAL CHARACTERISTICS—MAX6037_ADJ (VOUT = 1.184V to 5V) (continued)

(VIN = VSHDN = +5V, IOUT = 0, TA = TMIN to TMAX, ADJ shorted to OUT unless otherwise noted. Typical values are at TA = +25°C.)

Note 1: All devices are 100% 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 / VOUT is divided by the maximum ∆T.

Note 3: Thermal hysteresis is defined as the change in +25°C output voltage before and after cycling the device from TMAX to

TMIN.

Note 4: Not production tested. Guaranteed by design.

Note 5: Dropout voltage is defined as the minimum differential voltage (VIN - VOUT) at which VOUT decreases by 1% from its origi-

nal value at VIN = +5.0V.

Note 6: VOUT initial accuracy for the MAX6037_ADJ is tested with ADJ shorted to OUT. Actual accuracy will be affected by match-

ing and the temperature coefficient of the external resistors used. Use 1% resistors with low temperature coefficient for

best overall accuracy.

Note 7: The temperature coefficient for the MAX6037_ADJ is specified for the case where ADJ is connected to OUT. For the case

where an external resistive network is used to set the output voltage, actual change in reference output over temperature

will be affected by the temperature coefficient and matching of the external resistors used.

Note 8: The minimum VIN is the greater of +2.5V and (VOUT + 0.2V).

Note 9: VOUT set to +5V with an external resistive-divider.

Note 10: Noise for the MAX6037_ADJ is specified for a +1.25V output. Noise is proportional to VOUT and is greater for higher output

voltages. In addition, external resistors used to set the output voltage can contribute to noise.

Typical Operating Characteristics

(VIN = +3V for the MAX6037_12 and MAX6037_21; VIN = +5V for the MAX6037_25, MAX6037_30, MAX6037_33, and MAX6037_41;

IOUT = 0, COUT = 0.1µF, CIN = 0.1µF, TA = +25°C, unless otherwise specified.)
