The NJM2845/46 from New Japan Radio Co. Ltd is a low dropout voltage (LDO) regulator that features high precision output (1 percent), high ripple rejection (75dB typical at f=1kHz) and low dropout voltage (0.18V typical at Io=500mA). According to the company, the advanced bipolar technology utilized enabled the device to achieve these features.

With an output current of 800mA (max), the NJM2845 is 3 terminal type and the NJM2846 is an ON/OFF control built-in type. Packaging options include TO252 (3-pin) and TO252 (5-pin).
