1 / 12 page ACE504A Technology Wide Input Voltage Range, 150mA ULDO Regulator VER 1.2 1 Description ACE504A series are positive voltage regulator IC fabricated by high voltage EPNP process. The ACE504A has features of wide input voltage range and high accuracy, high ripple rejection, low dropout voltage, low noise, current limit and ultra-low quiescent current which make them ideal for use in various USB and portable device. The IC consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection, and a chip enable circuit. ACE504A has adjustable, 1.8V,3.3V,5.0V fixed voltage versions. The ACE504A is available in space saving SOT-23-5 an SOT-89-3 packages. Features • Wide Input Voltage Range: 2.3V to 24V • Wide Output Voltage Range: 1.24V to 22V • Excellent Ripple Rejection: 60dB@ f=1kHz • Low Dropout Voltage: V DROP=100mV@IOUT=100μA • Low Ground Current • High Output Voltage Accuracy • Compatible with Low ESR Ceramic Capacitor • Excellent Line/ Load Regulation • Thermal Shutdown Function Application • Battery Powered equipment • Laptop, Palmtops, Notebook Computers • Portable Information Appliances Absolute Maximum Ratings Parameter Symbol Max Unit Supply Input voltage VIN 38 V Enable Input Voltage VCE 38 V Output Current IOUT 250 mA Lead Temperature (Soldering, 10sec) TLEAD 260 ℃ Operating Junction Temperature TJ 150 ℃ ESD (Machine Mode) 275 V ESD (Human Body Mode) 2000 V Storage Temperature Range TLEAD -60 to 150 ℃ SOT-23-5 250 Thermal Resistance (No Heatsink) θJA SOT-89-3 165 ℃ /W Note 1: Stressed greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “ Recommended Operating Conditions” is not implied. Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability. |
