A7501
Overview
- Low voltage operation: Start up at 0.9V min switching regulator that mainly consists of a reference (IOUT=1mA) guaranteed voltage source, an oscillator, and a comparator.
- Low input current: During maximum operation: Enabling products with a low ripple over a wide range, high efficiency, and high output current.
- 18μA (VOUT=3.3V, typ.) Duty ratio: 77% Built-in fixed-type PFM Products with a fixed duty ratio of 75 %（Lower Output controller Voltage）or 88%(Higher Output Voltage) are also
- External parts: Coil, capacitor, and diode available. With the A7501 Series, a step-up switching
- Output voltage: Settable to between regulator can be configured by using an external coil,
- 5V to 5.5V , accuracy of 2% capacitor, and diode. A protection circuit turns off the built-in MOSFET when the voltage at the CONT pin exceeds the limit to prevent it from being damaged. This feature, along with the mini package and low current consumption, makes the A7501 Series ideal for applications such as the power supply unit of portable equipment.
- Available in SOT-89-3 and SOT-23 Packages
