Linear Regulator - Low Dropout 1.5 A NCP565, NCV565 The NCP565/NCV565 low dropout linear regulator will provide 1.5 A at a fixed output voltage or an adjustable voltage down to 0.9 V. www.onsemi.com The fast loop response and low dropout voltage make this regulator ideal for applications where low voltage and good load transient MARKING response are important. Device protection includes current limit, short DIAGRAMS circuit protection, and thermal shutdown. 2 1 D PAK 3 2 NC CASE 936 Features 3 FIXED y565D2Txx Ultra Fast Transient Response ( 1.0 s) AWLYWWG Tab = Ground Low Ground Current (1.5 mA at Iload = 1.5 A) Pin 1.
