产品概述 返回TOP
The CXSD62439 is a low supply current, low dropout linear regulator that comes in a space saving TSOT-23-5, package. The supply current at no-load is 100μA. In the shutdown mode, the maximum supply current is less than 1μA. The over-current protection limit is set at 430mA typical. An overtemperature protection circuit is built-in in the CXSD62439 to prevent thermal overload. These power saving features make the CXSD62439 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. These devices feature a shutdown function and are offered in active low with auto discharge. The CXSD62439 is specifically designed to employ ceramic output capacitors. The CXSD62439 comes in a space saving TSOT-23-5 package
