uP7706
3A Ultra Low Dropout Linear
Regulator
General Description
Features
The uP7706 is a 3A ultra low dropout linear
regulator specifically designed for motherboard and notebook applications. This device works with dual supplies, a control input for the control circuitry and a power input as low as 1.2V for providing current to output. The uP7706 delivers high-current and ultra-low-drop output voltage as low as 0.8V for applications where VOUT is very close to VIN. The uP7706 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 uP7706 is available in PSOP-8 or VDFN6x5-8L packages with very low thermal resistance.
