(1) Only valid for the TPS3801J25, TPS3801L30, TPS3801K33, TPS3801I50, and TPS3801T50.
(2) The lowest supply voltage at which RESET becomes active. t
r, 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.
