LOW DROP OUT VOLTAGE REGULATOR

■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE

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 C2. 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 VIN to be able

to stand for brake down voltage, current volume, and then less volume

for Vf.
