The AME8801/8812/8840 family is a series of positive, linear regulators with low quiescent current and low dropout voltage, making them ideal for battery applications. They feature low dropout voltage, guaranteed 300mA output, accuracy within 1.5%, low quiescent current of only 30µA, over-temperature shutdown, current limiting, short circuit current fold-back, noise reduction bypass capacitor, power-saving shutdown mode, etc.
The AME8801/8812/8840 family of positive linear regulators features low quiescent current (30µA typ.) with low dropout voltage, making them ideal for battery applications. These rugged devices include Thermal Shutdown and Current Fold-back to prevent device failure under worst-case operating conditions. They are available in space-saving SOT-23-5 and SOT-26 packages with factory pre-set output voltages ranging from 1.5V to 5.0V.
| Output Current | 300mA |
|---|---|
| Quiescent Current | 30µA typ. |
| Output Voltage Accuracy | 1.5% |
| Operating Temperature Range | -40°C to +85°C |
| Thermal Resistance (qja) | 260°C/W |
| Maximum Junction Temperature | 150°C |
The device is stable with an output capacitance of 2.2µF or greater.
The over-temperature shutdown circuit becomes active and the output voltage remains low.
The dropout voltage is 400mV when the input voltage is between 2.0V and 2.8V.
