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.

Features

• Pb−Free Packages are Available

• Ultra Fast Transient Response (t1.0 ms)

• Low Ground Current (1.1 mA @ Iload = 1.5 A)

• Low Dropout Voltage (0.9 V @ Iload = 1.5 A)

• Low Noise (28 mVrms)

• 0.9 V Reference Voltage

• Adjustable Output Voltage from 7.7 V down to 0.9 V

• 1.2 V Fixed Output Version. Other Fixed Voltages Available on

Request

• Current Limit Protection (3.5 A)

• Thermal Shutdown Protection (155°C)

Typical Applications

• Servers

• ASIC Power Supplies

• Post Regulation for Power Supplies

• Constant Current Source
