Descriptionspan id="lblDescription">
The AAT3220 PowerLinear NanoPower Low Dropout Linear Regulator is ideal for portable applications where extended battery life is critical. This device features extremely low quiescent current which is typically 1.1A. Dropout voltage is also very low, typically less than 225mV at the maximum output current of 150mA. The AAT3220 has output short-circuit and over-current protection. In addition, the device has an over-temperature protection circuit that will shutdown the LDO regulator during extended over-current events. Since only a small, 1F ceramic output capacitor is required, often the only space used is that occupied by the AAT3220 itself. The AAT3220 is truly a compact and cost-effective voltage conversion solution. The AAT3220 is available in a space-saving SC59 package or a SOT89 for applications requiring increased power dissipation. The device is rated over the -40C to +85C temperature range.
The AAT3220 PowerLinear NanoPower low dropout (LDO) linear regulator is ideal for portabl applications where extended battery life is critical. This device features extremely low quiescent current, typically 1.1A. Dropout voltage is also very low, typically less than 225mV at the maximum output current of 150mA. The AAT3220 has output short-circuit and over-current protection. In addition, the device also has an over-temperature protection circuit which will shut down the LDO regulator during extended over-current events.
The AAT3220 is available in a Pb-free, space-saving SC59 package, or a Pb-free SOT-89 package for applications requiring increased power dissipation. The device is rated over the -40°C to +85°C temperature range. Since only a small, 1F ceramic output capacitor is required, often the only space used is that occupied by the AAT3220 itself. The AAT3220 is truly a compact and cost-effective voltage conversion solution.
The AAT3221/2 is a similar product for this application, especially when a shutdown mode is required for further power savings.
