ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 5V, unless otherwise specified. (Note 3)

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device reliability

and lifetime.

Note 2: All currents into pins are positive, all voltages are referenced to GND

unless otherwise noted.

Note 3: The greater of V1, V2 is the internal supply voltage (VCC).

Note 4: Under static no-fault conditions, V1 will necessarily supply quiescent

current. If at any time V2 is larger than V1, V2 must be capable of supplying

the quiescent current, programming (transient) current and reference load

current.

Note 5: The output pins RST and COMPn have diode protected internal pull-ups

to V2 of typically 6μA. However, external pull-up resistors may be used when

faster rise times are required or for VOH voltages greater than V2.
