AX6608A 300m A Low Dropout Linear Regulator  GENERAL DESCRIPTION The AX6608A is a low dropout, high PSRR, low noise linear regulator with very low quiescent. It can supply 300m A output current with low dropout about 250m V. The Device includes pass element, error amplifier, band-gap, current-limit and thermal shutdown circuitry. The characteristics of low dropout voltage and less quiescent current make it good for some critical current application, for example, some battery powered devices. The typical quiescent current is approximately 30µA. Built-in current-limit and thermal-shutdown functions prevent any fault condition from IC damage. The AX6608A series are offering three different fixed output voltage types including 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3V and 3.3V. They are available in low-profile, space-saving 3-lead SOT23 package.  Features Input voltage range : 2.8V~5.5V Dropout voltage is 250m V at 300m A output current Guaranteed 300m A output current Low quiescent current is 30µA (typ.) ±2% Output voltage accuracy for 1.0V, 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3V and 3.3V Needs only 1u F capacitor for stability Fast transient response Current limit and thermal shutdown protection Available in the SOT23-3L Package VÛmw`R- yÑb€  BLOCK DIAGRAM w.goftechm VIN Error Amp VOUT Current Limit Thermal Shutdown - + Vref=1.2V GND 1/9 Axelite Confidential Materials, do not copy or distribute without written consent.

The input capacitor in VIN the range of 1u F to 10u F is sufficient. GND Ground Output Voltage, The AX6608A is stable with an output capacitor 1u F for greater. The larger output capacitor will be required for VOUT application with large transit load to limit peak voltage transits, besides could reduce output noise, improve stability, PSRR. Name ...
