ACE513 2A Linear Regulator Description ACE513 series are a group of positive voltage output, high precise, 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. ACE513 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: 26uA at 5V • High PSRR: 60dB range to 1KHz • Low Output Noise: 44uVRMS • Low Dropout: 430mV at 1.5A load • Maximum output current: 2.5A • Highly Accurate: ±2% • Low ESR Ceramic Capacitor Compatible Application • Reference Voltage Source • Battery Powered Equipment • PC Peripherals • Wireless Devices • Instrumentation Absolute Maximum Ratings Parameter Symbol Max Input voltage VIN 8 Unit V Operating Junction Temperature TJ 125 O Ambient Temperature TA -40~85 O Package Thermal Resistance Storage temperature SOT-223 20 TS - 40 to 150 O C C C/W O C Note: Exceed these limits to damage to the device. Exposure to absolute maximum rating conditions may affect device reliability. Typical Application Note: Input capacitor (Cin=4.7uF) and Output capacitor ACE513 (Cout=10uF) are recommended in all application Circuit (Low ESR ceramic capacitor is available) VER 1.2 1 ACE513 2A Linear Regulator Dropout Voltage vs Output Current Packaging Type SOT-223 1 2 SOT-223(A) SOT-223(B) Description 1 3 VDD 2 1 GND 3 2 VOUT 3 Recommended work conditions Parameter Value Input Voltage Range Max. 6V Ambient Temperature -40 ~ 85 OC Ordering information ACE513 XX XXX + H Halogen - free Pb - free XMA : SOT-223(A) XMB : SOT-223(B) Output Voltage : 2.5 / 3.3V……3.6V VER 1.2 2 ACE513 2A Linear Regulator Electrical Characteristics Test conditions: CIN=1uF, COUT=4.7uF, TA=25℃, unless otherwise specified.
