Enpirion Power Datasheet EY1602 40V, Low Quiescent Current, 50mA Linear Regulator DS-1046 Datasheet NOT RECOMMENDED FOR NEW DESIGN The Altera Enpirion EY1602 is a wide input voltage Features range, low quiescent current linear regulator ideally Wide V range of 6V to 40V IN suited for always-on and keep alive applications. The EY1602 operates from an input voltage of +6V to Adjustable output voltage from 1.223V to 12V +40V under normal operating conditions, consuming Guaranteed 50mA output current only 18A of quiescent current at no load. Ultra low 18A typical quiescent current The EY1602 has an adjustable output voltage range from Low 1.8A of typical shutdown current 1.223V to 12V. It features an EN pin that can be used to put the device into a low-quiescent current shutdown 1% accurate voltage reference mode where it draws only 1.8A of supply current. The Low dropout voltage of 120mV at 50mA device features automatic thermal shutdown and current 40V tolerant logic level (TTL/CMOS) enable input limit protection. Stable operation with 10F output capacitor The EY1602 is rated over the -40C to +125C temperature range and is available in an 8 lead EPSOIC 5kV ESD HBM rated with exposed pad package..
