ACE506C 300mA Low Consumption Linear Regulator Description ACE506C series are a group of positive voltage output, high precise, and high PSRR and low power consumption voltage regulator. Voltages are selectable in 100mV steps within a range of 1.2V to 3.6V. It also can be customized on command. ACE506C series have excellent load and line transient response and good temperature characteristics, which can assure the stability of chip and power system. And it uses trimming technique to guarantee output voltage accuracy within ±2%. Features • • • • • • • Low Quiescent Current: 2uA at 5V 60dB PSRR at 100Hz Low Output Noise: 44uVRMS Low Dropout: 280mV at 150mA load Low Temperature Coefficient: ±100ppm/ OC Excellent Line Regulation: 0.05%/V Highly Accurate: ±2% Application • • • • • Reference Voltage Source Battery Powered Equipment Hand-Hold Equipment Wireless LAN GPS Receivers Absolute Maximum Ratings Parameter Value Max Input Voltage 8V Operating Junction Temperature (TJ) 125 OC Ambient Temperature (TA) -40 OC ~85 OC Power Dissipation SOT-23-3, SOT-23-5 250mW SOT-89-3 500mW Storage Temperature (TS) -40 OC~150 OC Lead Temperature & Time 260OC, 10 Sec Note: Exceed these limits to damage to the device. Exposure to absolute maximum rating conditions may affect device reliability.
