AP7173-SPG-13 is a 3.0-5.5V step-down dc-dc regulator with high-efficiency, low-noise, fast transient response and programmable output voltage. It includes a die-integrated low drop-out (LDO) linear regulator and an adjustable current limit. It is ideal for providing system power in small portable electronic applications such as automated test equipment, mobile phones, digital cameras and other small consumer electronic products.The AP7173-SPG-13 is a highly efficient and low dropout voltage regulator with a peak efficiency of up to 95%. It offers a wide output range from 0.9V to 5.5V, selectable via external resistor dividers, and is capable of supplying up to 1.3A continuous load current over the entire operating input voltage range. Flexible power management features such as adjustable current limit, low quiescent current, adjustable soft start, and output voltage tracking enable optimized system performance, in combination with complete protection features like over-current protection and over-temperature protection.The AP7173-SPG-13 uses a combination of a delay ramp loop and a hysteretic control loop for regulating its output voltage. The output voltage is set using an external resistive voltage divider, and it is adjusted using the Input/Output (I/O) voltage rail. The delay ramp loop senses the I/O voltage and provides a soft turn-on feature by ramping it up slowly and minimizing the inrush current. The hysteretic control loop senses the output voltage and regulates the output within a 200mV band while the output load is varying.The AP7173-SPG-13 also features an adjustable current limit and a low quiescent current, allowing it to be used in battery-powered systems. The adjustable current limit can be configured to limit the load current as a function of the I/O voltage, or it can be set to a fixed value. The low-quiescent current allows the use of portable applications requiring long battery life. The AP7173-SPG-13 is integrated into a tiny SOT-23 package, and is highly reliable and stable. It meets the most stringent specifications for mobile and other power sensitive applications. The AP7173-SPG-13 is suitable for applications requiring both high efficiency and programmable output voltage. It is ideal for portable consumer applications such as digital cameras, handheld game consoles and smart cellular phones.In conclusion, the AP7173-SPG-13 is a highly efficient and low dropout Voltage Regulator with high performance, low noise, fast transient response and programmable output voltage. It delivers outstanding performance and reliability for portable consumer electronic products and mobile devices.
