| GENERAL DESCRIPTION The AMS2907 series of adjustable and fixed voltage regulators are designed to provide 500mA output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1%. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry. The AMS2907 devices are pin compatible with other three-terminal regulators and are offered in the low profile surface mount TO-252(DPAK), SOT-223 and SOT-89 packages. FEATURES • Three Terminal Adjustable or Fixed Voltages* 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5.0V • Output Current of 500mA • Operates Down to 1V Dropout • Line Regulation: 0.2% Max. • Load Regulation: 0.4% Max. • TO-252, SOT-223 and SOT-89 packages APPLICATIONS • High Efficiency Linear Regulators • Post Regulators for Switching Supplies • 5V to 3.3V Linear Regulator • Battery Chargers • Sound Cards • Power Management for Notebook • Battery Powered Instrumentation |
