ZHCSCW6B August 2014 – January 2018 LM43601
PRODUCTION DATA.
The EN pin provides electrical ON and OFF control for the LM43601. When VEN is below 0.4 V, the device is in shutdown mode. Both the internal LDO and the switching regulator are off. In shutdown mode the quiescent current drops to 1 µA typically with VIN = 12 V. The LM43601 also employs UVLO protection. If VCC voltage is below the UVLO level, the output of the regulator turns off.
