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.

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device.
These are for stress ratings. Functional operation of the device at these or any other conditions beyond those
indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may remain possibility to affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution recommended.
Note 3. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of
JEDEC 51-3 thermal measurement standard.
Note 4. The device is not guaranteed to function outside its operating conditions.
