Abstract: The present disclosure provides a ketone carbonyl-containing hydrophobic antitumor drug and a conjugate thereof as well as a nano preparation containing the conjugate, a preparation method therefor, and an application thereof. The conjugate is an amphipathic pH-responsive conjugate obtained by enabling a dehydration condensation reaction between a hydrazide-terminated polyethylene glycol and/or lactose hydrazide and the ketone carbonyl-introduced hydrophobic antitumor drug. The ketone carbonyl-introduced hydrophobic antitumor drug is obtained by reacting an isocyanate group in a compound containing isocyanate group and ketone carbonyl group with a hydroxyl on a hydroxyl-containing hydrophobic antitumor drug. The hydroxyl-containing hydrophobic antitumor drug includes at least one of paclitaxel, docetaxel, paclitaxel derivatives, or docetaxel derivatives.

Abstract: An LDO power supply circuit includes an operational amplifier, a first transistor, and a resistance feedback network including a first branch and a second branch. A negative electrode input end of the operational amplifier connects a control voltage. An output end of the operational amplifier connects a gate electrode of the first transistor. A source electrode of the first transistor connects a power supply voltage. A positive electrode input end of the operational amplifier and a drain electrode of the first transistor are respectively an input end and an output end of the LDO power supply circuit. The resistance feedback network connects between the drain electrode of the first transistor and the positive electrode input end of the operational amplifier. A first feedback coefficient formed by the first branch is different from a second feedback coefficient formed by the second branch. The present disclosure further provides a power amplifier.
