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
reliabilty and lifetime.
Note 2: The greater of V1, V2 is the internal supply voltage (V
LTC2908-A1 and the LTC2908-B1. V1 is the internal supply voltage (V
for the LTC2908-C1.

Note 3: All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.
Note 4: Under typical operating conditions, most of the quiescent cur-
rent is drawn from the V1 input. When V2 exceeds V1, V2 supplies most
of the quiescent current.
Note 5: The output pin RST has an internal pull-up to V
6μA. However, an external pull-up resistor may be used when a faster
rise time is required or for V
