Wide Input Voltage Ultra-Low Quiescent Current Regulator from Diodes Incorporated covers 5V, 9V, 12V, and 24V Power Rails

Diodes » AP7381

Diodes Incorporated introduced the AP7381. Operating from a wide input voltage spanning 3.3 V to 40 V, this positive voltage regulator offers ultra-low quiescent current and high accuracy, making it well-suited for use in a variety of applications ranging from USB and portable devices to energy meters and home automation.

Diodes - AP7381

The AP7381 is offered with fixed output voltages of 3.3 V or 5 V to power standard logic device supplies and I/O levels and can operate from an input voltage between 3.3 V and 40 V, which covers most common system power rails. The device provides excellent line and load regulation and features a low dropout voltage of typically 1000 mV for a 3.3 V output device operating at an output current of 100 mA. An internal voltage reference ensures output accuracy at room temperature is maintained within ±2%.

A low quiescent current of just 2.5 µA minimizes 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 also features over-current protection, provided by an internal current limit circuit.

The AP7381 is available in a SOT89 package (on tape & reel) and in a TO92 package (ammo packed).
