LTC2900
2900f
The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 5V, unless otherwise noted. (Note 3)
ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
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 RST output pin on the LTC2900-1 has an internal pull-up to V2
of typically 6
A. However, an external pull-up resistor may be used when
faster rise times are required or for VOH voltages greater than V2.
Note 6: The push-pull RST output pin on the LTC2900-2 is
actively pulled up
to V2.
