Note 5: The RST output pin on the LTC2903-1 has an internal pull-up to
V2 (for options A1, B1 and C1) of typically 10µA. However, for faster rise
times or for V
The internal pull-up is connected to V1 for options D1 and E1.
Note 6: For options A1, B1 and C1, the RST pulldown current is derived
from V1, V2 and V3. For options D1 and E1, pulldown strength is derived
from V1.
