오토모티브용 0.5A 가변출력 / 고정출력 LDO 레귤레이터
BD00IA5MEFJ-M
오토모티브용 0.5A 가변출력 / 고정출력 LDO 레귤레이터
BDxxIA5MEFJ-M 시리즈는 출력전류 0.5A 공급이 가능한 레귤레이터로, 출력 정밀도는 ±1%입니다.
외장 저항을 통해 0.8V~4.5V까지 임의의 출력전압을 설정할 수 있는 가변 타입과 1.0V / 1.2V / 1.5V / 1.8V / 2.5V / 3.0V / 3.3V 출력의 고정 타입을 구비하고 있습니다. 패키지는 방열성이 우수한 HTSOP-J8을 채용하고 있습니다.
본 기종은 출력 단락 등으로 인한 IC 파괴를 방지하는 과전류 보호, 셧다운 시의 회로전류를 0μA로 억제하는 ON / OFF 스위치, 과부하 상태 등으로 인한 열파괴로부터 IC를 보호하는 온도 보호회로를 내장하고 있습니다.
또한, 세라믹 콘덴서 대응으로 세트의 소형화 및 장수명화에 기여합니다.

- CISPR25 Class5 compliant 8 rails power tree Reference Design for Automotive ADAS/Infotainment application
This reference design is a power tree solution board developed for infotainment devices such as automotive clusters and center information displays and for ECUs for ADAS application. The power system that can support functional safety is integrated on a single board to achieve the optimal configuration as a power tree. Excellent EMC performance that meets CISPR25 Class 5 even at all power supply rails are enabled, and reduces heat generation of each device by distributing high-efficiency DCDCs. In addition, two supervisor ICs with self-diagnosis functions can monitor the output of all power rails and contribute to a higher level of functional safety.
- Automotive Infotainment/ADAS 8-channels power tree reference design
- Verified to satisfy EMC CISPR 25 class 5 standard without common mode filter
- In order to avoid the AM radio frequency bands All DC/DC converters operate at a switching frequency of 2.2 MHz or higher.
- Thermal characteristics tested
- voltage monitoring for 8-channel power tree to improve the functional safety ASIL level
- Space saving by integrating multiple power trees
