uP7701
3A Ultra Low Dropout Linear
Regulator
General Description
Features
The uP7701 is a 3A ultra low dropout linear
regulator specifically designed for motherboard,notebook and graphic card applications. This device works with dual supplies, a control input for the control circuitry and a power input as low as 1.0V for providing current to output. The uP7701 delivers high-current and ultra-low-drop output voltage as low as 0.8V for applications where VOUT is very close to VIN. The uP7701 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 foldback current limit function, and a thermal shutdown function.
The uP7701 is available in PSOP-8 package with very low thermal resistance.
