NJM2884/A
LOW DROPOUT VOLTAGE
REGULATOR
GENERAL DESCRIPTION The NJM2884/A is a low dropout voltage
regulator with ON/OFF control. Advanced Bipolar technology achieves low noise, high ripple rejection and low quiescent current. It delivers up to 5V/500mA output power with the maximum input voltage of 10V. The NJM2884/A is suitable for audio/video and PC related applications. The “U2” suffix product achieves high PD compared with “U1” although the same package outline (SOT-89-5) .
