It produce aregulated output voltage from a 2.7V to 4.5Vinput. Low external parts count (one flyingcapacitor and two small bypass capacitors atVIN and VOUT) make the HE9119A ideallysuited for small, battery-powered applications.The HE9119A have thermal shutdowcapability and can survive a continuous shortcircuit from VOUT to GND. A low currentshutdown feature disconnects the load from VINand reduces quiescent current to <1uA.The HE9119A is available in the indu
