Enpirion Power Datasheet EY1603 40V, Low Quiescent Current, 150mA Linear Regulator DS-1047 Datasheet NOT RECOMMENDED FOR NEW DESIGN The Altera Enpirion EY1603 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 EY1603 operates from an input voltage of +6V to Adjustable Output Voltage from 1.223V to 12V +40V under normal operating conditions and consumes Guaranteed 150mA Output Current only 18A of quiescent current at no load. Ultra Low 18A Typical Quiescent Current The EY1603 has an adjustable output voltage range from Low 2A of Typical Shutdown Current 1.223V to 12V. The EY1603 features an EN pin that can be used to put the device into a low-quiescent current 1% Accurate Voltage Reference shutdown mode where it draws only 2A of supply Low Dropout Voltage of 295mV at 150mA current. The device features automatic thermal 40V Tolerant Logic Level (TTL/CMOS) Enable Input shutdown and current limit protection. Stable Operation with 10F Output Capacitor The EY1603 is rated over the -40C to +125C temperature range and is available in a 14 lead HTSSOP 5kV ESD HBM Rated with an exposed pad package.
