MCP1722 - High Voltage Dual Output LDO

 

MICROCHIP

 

Description

MCP1722는 3.3V 또는 5.0V를 μProcessor에 공급하도록 설계된 듀얼 출력, 고전압, 저드롭아웃(LDO) 레귤레이터입니다. 전류 용량은 100mA이며, 전류 용량이 50mA인 모터 드라이버에 10V 또는 12V를 제공합니다. 이러한 사양은 20V 배터리 팩이 있는 핸드헬드 전동 공구에 이상적입니다.

MCP1722에는 두 출력에 대한 Power Good 표시기(PWG1 및 PWG2의 두 핀)와 부품을 4μA의 낮은 전류 소비 상태로 만드는 셧다운 기능(단일 SHDN 핀)이 함께 제공됩니다.

이 장치는 두 개의 8리드 DFN 또는 SOIC 패키지로 제공되며, 둘 다 노출된 패드가 있어 열 발산이 개선되었습니다. 작동 중 MCP1722는 열 셧다운 보호 및 전류 폴드백 제한으로 완벽하게 보호됩니다.
