LDO 稳压器,500 mA,带快速启动

Favorite

概览

CAT6219 是一款 500 mA CMOS 低漏稳压器,在负载电流和线路电压变化期间提供快速响应时间。 快速启动特性允许使用外部旁通电容器,可降低总体输出噪声,而不会影响仅为 150 µs 的导通时间。 CAT6219 的零关断电流和 55 µA 的低静止电流典型值使其适用于基于 2.3 V 至 5.5 V 电源电压运行的电池供电设备。内部欠压锁定电路会在低于 2.15 V 典型值的电源电压下禁用输出。 CAT6219 提供 1% 的初始准确性和低漏电压,500 mA 时的典型值为 300 mV。小型陶瓷输出电容器提供了稳定运行,减少了所需板空间和组件成本。 其他特性包括电流限值和高温保护。 该 LDO 提供固定和可调输出,采用薄型 (最大高度 1 mm)5 引线 TSOT23、6 焊盘 1.5 mm x 1.5 mm WDFN 和 6 焊盘 2 mm x 2 mm TDFN 封装。
