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 (V
Note 4: 10% thresholds apply to the LTC2901-3/LTC2901-4 only when the
TOL pin is set to a logic high.

Note 5: 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 6: The output pins RST, WDO and COMPX have internal pull-ups to V2
of typically 6μA. However, external pull-up resistors may be used when faster
rise times are required or for V
Note 7: The push-pull RST output pin on the LTC2901-2/LTC2901-4 is
actively pulled up to V2.
