NJM2351

The NJM2351 is designed as multi output voltage regulator with positive output, negative output and positive five peices output, which can deliver up to 200mA output current with additional external transistors. System A in positive and negative output of NJM2351 have ripple filter internally for audio system. System B positive output is applied for system control.

NJM2351 has five features. (1) Operating voltage is from 13V to 21V. (2) Dual supply operation. (3) Internal ripple filter circuit. (4) Package outline DIP16. (5) Bipolar technology. That are all the main features.

Some absolute maximum ratings of NJM2351 have been concluded into several points as follow. (1) Its input voltage is +/-22V. (2) Its output current would be +4mA for pin 2 and -4mA for pin 7 and +8mA for pin 14, 16 and pin 9 for -8mA. (3) Its power dissipation is 700mW. (4) Its operating temperature range is from -10°C to +75°C. (5) Its storage temperature range is from -40°C to +125°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.
