FLD0503-2.8YSOT235G/TR

FLD0503 500nA IQ, 300mA Low-Dropout Linear Regulator Description Features The FLD0503 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 500nA quiescent current at no load, the FLD0503 is ideally suited for standby microcontrol-unit systems, especially for always-on applications like portable, and other battery operated systems. The FLD0503 retains all of the features that are common to low dropout regulators including a low dropout PMOS pass device, short circuit protection, and thermal shutdown. The FLD0503 has a 6V maximum operating voltage limit, a 0°C to 100° C operating temperature range, and ± 2% output voltage tolerance over the entire output current, input voltage, and temperature range. The FLD0503 is available in SOT89-3, SOT23-5, and DFN1X1 surface mount packages. ⚫ VIN Range up to 6V ⚫ Output Voltage Tolerances of ±2% Over the Temperature Range ⚫ Output Current of 300mA, Supports ⚫ Ultar Low Quiescent Current (IQ = 450mA peak Output 500nA) ⚫ Dropout Voltage Typically 400mV at IOUT =300mA ⚫ Internal Thermal Overload Protection ⚫ Internal Short-Circuit Current Limit ⚫ Ceramic Capacitor Stable APPLICATIONS ⚫ ⚫ ⚫ Portable, Battery Powered Equipment Ultra Low Power Microcontroller Notebook computers TYPICAL APPLICATION Figure 1.Typicla Application for FLD0503 http://www.full-way.com/ 1 IC your Idea, we see the Future FLD0503 Figure 2.Typicla Application for FLD0503 PIN CONFIGURATION Figure 3.
