AP2210 300mA ULDO Regulator, 3.3V, SOT-23
AP2210 300mA ULDO regulator with ultra-low dropout, 1µA standby, and 75dB PSRR ideal for RF & battery devices.
The AP2210 is a 300mA ultra-low dropout (ULDO) regulator designed for battery-powered and noise-sensitive applications. With a typical dropout voltage of only 250mV at 300mA, this regulator ensures efficient operation even when the input voltage is close to the output voltage. Its ultra-low standby current of 1µA (maximum) maximises battery life in portable devices.
This LDO regulator delivers excellent power supply ripple rejection, with 75dB PSRR at 100Hz, making it ideal for RF electronics and other sensitive analog circuitry. The device offers fixed 3.3V output and operates from an input voltage range of 4.3V to 13.2V. It includes individual logic-compatible enable/shutdown controls, allowing for a low-power shutdown mode to further extend battery life.
The AP2210 is equipped with comprehensive protection features, including over-current protection, over-temperature protection, and reversed-battery protection, ensuring reliable operation in demanding environments. It is housed in a compact SOT-23 package with 5 pins, suitable for surface-mount assembly.
