Regulator ICs
BA3950A
(4)
An overcurrent protection circuit is installed in each out-
put system, based on the respective output current. This
prevents IC destruction by overcurrent, by limiting the
current with a curve shape of “7” in the voltage-current
graph. The IC is designed with margins so that current
flow will be restricted and latching will be prevented even
if a large current suddenly flows through a large capaci-
tor. Note that these protection circuits are only good for
preventing damage from sudden accidents. Make sure
your design does not cause the protection circuit to oper-
ate continuously under transitional conditions (for
instance, when output is clamped at 1V
F
or higher). Note
that the circuit ability is negatively correlated with temper-
ature.

A built-in thermal protection circuit prevents thermal
damage to the IC. All outputs are switched OFF when the
circuit operates, and revert to the original state when
temperature drops to a certain level.
(6)
Improving ripple rejection by capacitors
Ripple rejection of the CDP and MAIN outputs can be im-
proved by installing a capacitor that reduces the AC gain.
(7)
Malfunction in intense electric fields
Note that bringing the IC into an intense electric field
(such as a radio relay station) may result in malfunction.
