(1)
Only valid for the TPS3801J25, TPS3801L30, TPS3801K33, TPS3801I50, and TPS3801T50.
(2)
The lowest supply voltage at which RESET becomes active. tr, VDD ≥ 15 ms/V.
(3)
To ensure the best stability of the threshold voltage, a bypass capacitor (0.1-mF ceramic) should be placed near the supply terminals.
