NJM2930
LOW DROP OUT VOLTAGE REGULATOR
■
GENERAL DESCRIPTION
The
NJM2930
3-terminal positive voltage regulator features an
ability to source 150mA of output current (100mA: L-Type) with an
input-output differential of 0.6V or less. Efficient use of low input
voltages obtained, for example, from an automotive battery during
cold crank conditions, allows 5V circuitry to be properly powered with
supply voltages as low as 5.6V.
Familiar regulator features such as current limit and thermal
overload protection are also provided.

STANDARD APPLICATION EXAMPLES
* This
NJM2930
is required when the mounting position is separated from the power filter.
** Use an aluminum electrolytic capacitor or a tantalum capacitor as C
2
. The temperature guarantee range of
capacitors should be down to -30°C. A capacity value of 10µF is a minimum requirement for improving the stability
and transient response. Mount it at a position as close to the leads as possible.
*** When application on automobile car operation, the minus pulse might
be input on IC. In this case, however, the pulse might trigger to latch up.
If it were that, this kind of latching up might be continued, the IC would
burn up into defective in many cases. It is advisable to apply D1, D2
as described in the drawing, in order to prevent from making any
troubles. It is important to make devices D1, D2 against V
IN
to be able
to stand for brake down voltage, current volume, and then less volume
for Vf.
