NCP565 Datasheet, PDF (1/12 Pages) ON Semiconductor – 1.5 A Low Dropout Linear Regulator

NCP565
1.5 A Low Dropout
Linear Regulator
The NCP565 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. The NCP565 is packaged in a 5 pin
D²PAK for adjustable voltage version and a 3 pin D²PAK for fixed
voltage version.
