Single-Output LDO Regulators
35V Withstand Voltage
1A LDO Regulators
BDxxFC0 series
●Description
The BDxxFC0 series are low-saturation regulators. The
series’ output voltages are Variable, 3.0V, 3.3V, 5.0V, 6.0V,
7.0V, 8.0V, 9.0V, 10.0V, 12.0V and 15.0V and packages
are HTSOP-J8, TO252-3, and TO252-5. This series 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.
●Key
Specifications
1) Output current capability: 1A
2) Output voltage: Variable, 3.0V, 3.3V, 5.0V, 6.0V, 7.0V,
8.0V, 9.0V, 10.0V, 12.0V and 15.0V
3) High output voltage accuracy (Ta=25°C): ±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) Available Ceramic Capacitor to prevent oscillation
8) HTSOP-J8, TO252-3 and TO252-5 packages
