1 / 9 page ACE520 Dual 300mA High PSRR Linear Regulator VER 1.4 1 Description ACE520 dual, low-noise, low-dropout regulator delivers at least 300mA of continuous output current. The output voltage for each regulator is set independently by trimming. Output voltages are selectable in 100mV steps within a range of 1.2V to 3.5V. Typical output noise is 47uVrms,and PSRR is 73dB at 100Hz. The ACE520 includes two independent logic-controlled shutdown inputs and allows the output of each regulator to be turned of independently. The ACE520 includes high accuracy voltage reference, error amplifier, current limit circuit and output driver module. The ACE520 has 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 Two low dropout voltage regulators 300mA output current for each LDO 25uA operating supply current per LDO Low 47uV RMS output noise Standby Mode: 0.1uA Low 160mV dropout at 300mA load 73dB PSRR at 100Hz Excellent Line regulation: 0.05%/V Independent Shutdown controls 1.2V to 3.5V Factory-Preset Output Output Current Limit Highly Accurate: ±2% (±1% customized) Application Cellular phones Cordless phones and radio communication equipment Battery Powered equipment Notebook and hand-ole equipment Wireless LAN GPS receivers Absolute Maximum Ratings Parameter Symbol Max Unit Input voltage VIN 8 V Power Dissipation SOT-23-6 250 mW Junction temperature TJ 125 OC Storage temperature TS - 45 to 150 OC Ambient Temperature TA -40 to 85 OC Note: Exceed these limits to damage to the device. Exposure to absolute maximum rating conditions may affect device reliability. |
