General Description
The BDxxC0A-C series and the BDxxC0AW-C series are
low-saturation regulators. This series feature variable and
fixed voltage output with selectable Shutdown switch
(referred to as SW); Vout-3.3V, 5.0V, 8.0V and 9.0V.Five
conventional PKGs; TO252-3/5, HRP5 and TO263-3(F)/5
are available. 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.
Features
1) Output current capability: 1A
2) Output voltage: Variable, 3.3V, 5.0V, 8.0V and 9.0V
3) High output voltage accuracy
(Ta=25°C, TO252-3/5, HRP5): ±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) TO252-3/5, HRP5, TO263-3(F)/5 package
9) AEC-Q100 Qualified
(Note 1)
