The AME8890 is a 1.2V fixed output, low quiescent current (30µA) linear regulator with low dropout voltage, making it ideal for battery applications. The space-saving SOT-23-5 package is attractive for “Pocket” and “Hand Held” applications. This rugged device has both Thermal Shutdown and Current Fold-back to prevent device failure under the “Worst” of operating conditions.
The AME8890 is a fixed 1.2V output voltage CMOS LDO designed for battery applications requiring low dropout voltage and low quiescent current (30µA typical). It features protection mechanisms including thermal shutdown, current fold-back, and a power good detector to ensure device reliability under worst-case operating conditions.
The device is available in a space-saving SOT-25 package and operates over an ambient temperature range of -40°C to +85°C. Key specifications include a guaranteed 150mA output current, accurate voltage regulation within 3%, and stability with an output capacitor of 2.2µF or greater.
