Description
The SC561 is a dual output, ultra-low dropout linear
voltage regulator designed for use in battery powered
applications. The SC561 provides fixed output voltages of
V
= 3.1V and V
= 2.85V
, and up to 300mA of load
current per channel.
In applications where maximum battery life is essential,
the SC561 can operate in an extremely low power state by
setting the dynamic bias control. At very light loads, the
LOAD pin can be pulled low so that the device consumes
only 40μA of quiescent current.
The SC561 provides superior low-noise performance by
using an external bypass capacitor to filter the bandgap
reference. The device also has a PGOOD output to hold a
processor in reset when the voltage on OUTA is not in
regulation.
The device provides protection circuitry such as short-
circuit protection, under-voltage lockout, and thermal
protection to prevent device failures. Stability is main-
tained by using 1μF capacitors on the output pins. The
MLPQ-UT8 package and small ceramic bypass capacitors
minimize the required PCB area.
