The APL1117A is a low dropout positive adjustable or fixed-mode regulator with minimum of 1A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC aplications such as high-speed bus termination and low current 3.3V logic supply. The APL1117A is also well suitable for other applications such as VGA cards. It is guaranteed to have lower than 1.4V dropout at full load current, which makes it an ideal to provide wellregulated outputs of 1.25V to 5.0V with 6.4V to 12V input supply.
The APW7139 consists of two independent 1.3MHz constant frequency, current mode, PWM step-down converters. Each converter integrates a main switch with a synchronous rectifier for high efficiency without an external Schottky diode. The APW7139 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 800mA of load current from a 2.5V to 5.5V input voltage. The output voltage can be regulated as low as 0.6V. The APW7139 can also run at 100% duty cycle for low dropout applications.
The APW7079 is a compact, PFM mode, step-up DC-DC converter with low quiescent current. The internal synchronous rectifier reduces cost and PCB space by eliminating the need for an external Schottky diode. Low onresistance of the internal switches improves the efficiency up to 92%. The start-up voltage is guaranteed below 1V. After start-up, the device can operate with input voltage down to 0.7V. The APW7079 is suitable for portable battery- powered applications.
The APW7080 is a 4A, asynchronous, step-down converter with integrated 80mW P-channel MOSFET. The device, with current-mode control scheme, can convert 4.5~26V input voltage to the output voltage adjustable from 0.8 to 90% VIN to provide excellent output
