NJM2930 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 1. Input cold crank conditions, allows 5V circuitry to be properly powered with 2. GND supply voltages as low as 5.6V. 3. Output Familiar regulator features such as current limit and thermal overload protection are also provided. NJM2930F ■ FEATURES • Operating Voltage • Input-Output differential less 0.6V • Output Current in Excess of 150mA • 40V Load Dump Protection • Internal Short Circuit Current Limit • Internal Thermal Overload Protection • Package Outline TO-220F • Bipolar Technology ■ EQUIVALENT CIRCUIT Ver.2007-02-14 -1-

NJM2930 ■ 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. The temperature guarantee range of 2 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 to be able IN to stand for brake down voltage, current volume, and then less volume for Vf. ■ POWER DISSIPATION VS.
