AOZ2003
3A Ultra Low Dropout Linear
Regulator
General Description
The AOZ2003 is a 3A ultra low dropout linear
regulator designed for desktop motherboard, graphic card and notebook applications. This device needs dual supplies, a control voltage for the control circuitry and an input voltage for power conversion. The AOZ2003 delivers high-current and ultra low-drop output voltage for applications where VOUT is very close to VIN.
The AOZ2003 features comprehensive control and protection functions: a power on reset (POR) circuit for monitoring both control and power inputs for proper operation; an EN input for enabling or disabling the device, a power OK with time delay for indicating the output voltage status, a current limit function, and a thermal shutdown function.
The AOZ2003 is available in exposed pad SO-8 package.
