RT9078N-08GJ5-MS

The RT9078N-08GJ5-MS series is a family of low dropout (LDO) regulators featuring a wide input voltage range of 2V to 5.5V, low dropout voltage, low quiescent current, and compact packaging. The RT9078N-08GJ5-MS offers a quiescent current as low as 40uA, making it particularly well-suited for battery-powered devices and long-term standby applications. It helps reduce system standby power consumption, effectively extending standby time and battery life. The RT9078N-08GJ5-MS is available in a version with an EN enable pin; pulling the EN pin low puts the device into shutdown mode, in which the quiescent current can be as low as 1uA (typical). The RT9078N-08GJ5-MS series supports ceramic output capacitors and operates stably across the full 2V to 5.5V input voltage range and the entire output load current range of 0mA to 300mA.
