NCP565/NCV565
1.5 A Low Dropout
Linear Regulator
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.
The fast loop response and low dropout voltage make this regulator
ideal for applications where low voltage and good load transient
response are important. Device protection includes current limit, short
circuit protection, and thermal shutdown.
