Negative Charge Pump And Adjustable Regulator
The MP5418 is a monolithic negative charge pump with built-in adjustable negative regulator. Its input range is from 2.3V to 5.5V, MP5418 provide a unregulated output which equal to negative input voltage. And MP5418 also provide a regulated output between 0V and negative input voltage.
No external inductor is required for simplicity and compactness. Internal soft start circuit effectively reduces the in-rush current both while startup.
The MP5418 is available in a ultra low profile QFN 1.4mmx1.8mm package. MP5418 just requires 4 ceramic capacitors to get the minimal solution size. It is ideal for a wide range of applications include optical module, RF amplifier and sensor supply.

Negative Charge Pump and Adjustable Regulator
The MP5418 is a monolithic negative charge pump with a built-in adjustable negative regulator. It has an input range from 2.3V to 5V and provides an unregulated output equal to the negative input voltage. The MP5418 also provides a regulated output between 0V and the negative input voltage.
No external inductor is required, which reduces space and simplifies design. An internal soft-start circuit effectively reduces the in-rush current during start-up.
The MP5418 is available in an ultra-low profile QFN-10 1.4mmx1.8mm package. It requires only 4 ceramic capacitors for a compact solution size. It is ideal for a wide range of applications, including optical modules, RF amplifiers, and sensor supplies.
