DESCRIPTION
As a result, the EUP3504 helps to extend battery life and product operation time. Externally programmable soft-start allows for proper power on sequencing with respect to other power supplies and avoids input inrush current during startup. When a low signal is input to the EN pin, the IC enters shutdown mode. Even where a load capacitor is connected to the output pin during shutdown, the electric charge stored at the load capacitor is discharged through the internal switch. As a result, the VOUT pin voltage falls quickly to the GND level. The EUP3504 contains thermal shutdown protection. FEATURES
