530mV最大压差LT3973是我们不断成长的超低静态电流高电压单片式降压型稳压器系列的最新成员。该器件仅消耗1.8μA静态电流,并可从12V输入提供3.3V稳压输出。在芯片上内置了一个高效率开关以及箝位二极管、升压二极管和所有必需的控制器和逻辑电路。当输入电压降至编程输出电压以下时,可保持一个530mV的最小压差电压,从而为下游负载提供一个稳定的输出。其低纹波突发模
530mV Maximum Dropout The LT3973 is the newest addition to our growing portfolio of ultra-low quiescent current high-voltage monolithic step-down regulators. The device consumes only 1.8μA quiescent current and provides 3.3V regulated output from a 12V input. An on-chip built-in high-efficiency switch and clamp diodes, boost diodes and all necessary controllers and logic. When the input voltage drops below the programmed output voltage, a minimum differential voltage of 530mV can be maintained, providing a stable output for the downstream load.
