SPX1117 - 800mA Low Dropout Voltage Regulator

SPX1117 - 800mA Low Dropout Voltage Regulator

 

MAXLINEAR

 

DESCRIPTION
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, 3.3V, and 5V output voltages.

The SPX1117 is offered in a 3-pin SOT-223 surface mount package. An output capacitor of 10µF provides unconditional stability, while a smaller 2.2µF capacitor is sufficient for most applications.

 

SPX1117은 비용 효율적이고 작은 크기의 솔루션으로, 중간 정도의 전력 요구를 충족시키기 위해 설계된 저전력 양전압 레귤레이터입니다. 이 장치는 배터리로 구동되는 응용 제품과 휴대용 컴퓨터에 사용하기 적합합니다.

SPX1117은 매우 낮은 정지 전류와 최대 부하에서 1.1V의 낮은 드롭아웃 전압을 특징으로 합니다. 출력 전류가 감소할 때 정지 전류가 부하로 흘러 효율이 증가합니다. SPX1117은 조정 가능한 출력 또는 1.5V, 1.8V, 2.5V, 3.3V, 5V의 고정 출력 전압 옵션으로 제공됩니다.

SPX1117은 3핀 SOT-223 표면 실장 패키지로 제공되며, 무조건적인 안정성을 위해 10µF의 출력 커패시터가 필요하며 대부분의 응용 제품에는 2.2µF의 소형 커패시터도 충분합니다.

아들을 믿는 자에게는 영생이 있고 

아들에게 순종하지 아니하는 자는 영생을 보지 못하고 

도리어 하나님의 진노가 그 위에 머물러 있느니라
