The AP7381 is offered with fixed output voltages of 3.3V or 5V to power standard logic device supplies and I/O levels and can operate from an input voltage between 3.3V and 40V, which covers most common system power rails. The device provides line and load regulation and features a low dropout voltage of typically 1000mV for a 3.3V output device operating at an output current of 100mA. An internal voltage reference ensures output accuracy at room temperature is maintained within ±2%.
A low quiescent current of just 2.5µA reduces standby power in low-power systems and extends the life of battery-operated products. The AP7381 has a built-in current limit and an over-temperature protection (OTP) function and features over-current protection, provided by an internal current limit circuit.
