詳細說明
The NJM2389F is a low dropout voltage regulator (LDO) designed and manufactured by New Japan Radio Co., Ltd. It offers a compact and efficient solution for various electronic applications requiring stable voltage output. With a dropout voltage as low as 0.06V at 100mA load, it ensures efficient power management, making it suitable for battery-operated devices and low-power systems. The regulator can handle input voltages ranging from 2.0V to 6.0V, providing a regulated output voltage adjustable from 0.8V to 5.0V through external resistors. Its high ripple rejection ratio of 75dB (typical) helps maintain a steady output voltage even in noisy environments. Additionally, the NJM2389F features overcurrent protection and thermal shutdown circuitry, enhancing system reliability and preventing damage from excessive current or temperature. Its small surface-mount package (SOT-23-5) facilitates easy integration into space-constrained designs.
