Fonctionnalités et applications
Exar offers a broad array of power management integrated circuits (ICs) that are used in a wide variety of end applications.

Exar’s state of the art solutions provide high efficiency, low quiescent current, small size and the industry’s best price/performance ratio.

Many of Exar’s most advanced power management ICs are offered in thermally enhanced, lead-free DFN or QFN packages for the best blend of low thermal impedance and minimal circuit board area. 

Exar power management products can be used as stand alone solutions but are designed to be used together to create a complete power management system.  This product group includes low drop out linear regulators (LDOs), DC to DC switching regulators, PWM controllers, charge pumps, and microprocessor supervisors.

The SPX1117 is a low power positive-voltage regulator designed to satisfy moderate power requirements with a cost effective, small footprint solution. This device is an excellent choice for use in battery-powered applications and portable computers.

The SPX1117 features very low quiescent current and a low dropout voltage of 1.1V at a full load. As output current decreases, quiescent current flows into the load, increasing efficiency. SPX1117 is available in adjustable or fixed 1.5V, 1.8V, 2.5V,2.5V, 2.85V, 3.0V, 3.3V and 5V output voltages.

The SPX1117 is offered in several 3-pin surface mount packages: SOT-223, TO-252, TO-220 and TO-263. An output capacitor of 10μF provides unconditional stability while a smaller 2.2μF capacitor is sufficient for most applications.

SPX1117 Features:

  • Guaranteed 0.8A Output Current
  • Guaranteed 1A Peak Current
  • Three Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V and 5V
  • Low Quiescent Current
  • Low Dropout Voltage of 1.1V at 0.8A
  • 0.1% Line and 0.2% Load Regulation
  • Stable with 2.2uF Ceramic Capacitor
  • Overcurrent and Thermal Protection
  • Available Packages: SOT-223,TO-252, TO-220, and TO-263
