Ultra-low quiescent current regulator launched

Operating from a wide input voltage spanning 3.3V to 40V the AP7381 introduced by Diodes Incorporated is a positive voltage regulator that 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.

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 excellent 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 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)
