●General
Description
The BD80C0AFPS-M and BD90C0AFPS-M are
low-saturation regulators. These ICs have built in over
current protection to protect the device when output is
shorted and thermal shutdown circuit to protect the
device during over load conditions.
●Features
Output Current capability : 1A
High Output Voltage Precision: ±1%
Low saturation with PDMOS output
Built-in over-current protection circuit that prevents
the destruction of the IC due to output short circuits
Built-in thermal shutdown circuit for protecting the IC
from thermal damage due to overloading
Low ESR Capacitor
AEC-Q100 Qualified
●Applications
Audiovisual equipments, FPDs, televisions, personal
computers or any other consumer device
