BD80C0AFPS,BD90C0AFPS
●Description
The BD80C0AFPS, BD90C0AFPS is low-saturation regulator. This IC has a built-in over-current protection circuit that
prevents the destruction of the IC due to output short circuits and a thermal shutdown circuit that protects the IC from thermal
damage due to overloading.
●Features
1) Output Current: 1A
2) Output Voltage: 8.0V / 9.0V
3) High Output Voltage Precision: ±1%
4) Low saturation with PDMOS output
5) Built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits
6) Built-in thermal shutdown circuit for protecting the IC from thermal damage due to overloading
7) Low ESR Capacitor
8) TO252S-3 packaging
●Applications
Audiovisual equipments, FPDs, televisions, personal computers or any other consumer device
●Absolute maximum ratings (Ta=25℃)
