uP7704
2A Ultra Low Dropout Linear Regulator
General Description
Features
The uP7704 is a 2A 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 1.2V for providing current to output. The uP7704
delivers high-current and ultra-low-drop output voltage as
low as 0.8V for applications where VOUT is very close to
VIN.
The uP7704 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 uP7704 is available in PSOP-8 or WDFN3x3-10L
packages with very low thermal resistance.
