ZHCSGG8F July 2011 – March 2018 LM25118
PRODUCTION DATA.
The LM25118 contains an enable function which provides a very low input current shutdown mode. If the EN pin is pulled below 0.5 V, the regulator enters shutdown mode, drawing less than 10 µA from the VIN pin. Raising the EN input above 3 V returns the regulator to normal operation. The EN pin can be tied directly to the VIN pin if this function is not needed. It must not be left floating. A 1-MΩ pullup resistor to VIN can be used to interface with an open-collector or open-drain control signal.
