The AN80L18RMS is a high-performance 800mA low-dropout linear voltage regulator designed and implemented on an optimized high-voltage, low-dropout process. It provides a regulated output voltage of 1.8V following a set of adjustable output voltage options, within a wide input voltage range from VIN2.7V to VIN12V. Furthermore, this linear voltage regulator also provides excellent line and load transient response to ensure clean output power from noisy inputs, making it suitable for a wide range of system applications, including RF transceivers, wired/wireless combos, USB power applications, consumer electronics, and more.

The AN80L18RMS voltage regulator consists of several different components, each performing a specific task. The voltage reference, the low-dropout control block and the output switch are the primary blocks. The voltage reference provides a nominal reference voltage of 0.8V which is adjustable through external resistor. This reference voltage is compared with a feedback pin to control the switch in the high-side. The ON/OFF state of the switch is determined by the low-dropout control block, which is controlled by this voltage reference. Once the switch is turned ON, the power flow is commutated to the output switch which then provides a regulated output voltage of 1.8V.

The AN80L18RMS is designed to offer a wide variety of operating options. It can be used with Quiescent Current Mode Load Transient Adaptation (QLTA), which ensures an accurate output voltage across range of load transients with reduced total component dissipation. It also features fast response time with slew rate control as well as over current protection for safe operation. Furthermore, the EN/PG (Enable/Power Good) pin can be used to enable or disable the device and monitor the power supply status respectively. The device can also be enabled using an external selector. Additionally, the device is available in standard SOT23-5L and DFN-6L packages.

The AN80L18RMS is a high-performance voltage regulator which can be used in a wide range of system applications. Its high efficiency, low dropout operation, wide input voltage range and wide range of adjustable output voltages enable it to be used in many consumer applications such as cell phones, tablets, laptops, and other consumer electronics. Additionally, its fast response time and high efficiency make it suitable for RF and data transfer applications. Finally, this device ensures secure operation even under widely varying conditions, making it the ideal solution for mission-critical applications.
