Sillumin SLM5418EJ-7G

The SLM5418 is a monolithic negative charge pump with a built-in adjustable negative linear regulator. It has an input range from 2.3V to 5.5V and provides an unregulated output equal to the negative input voltage. The SLM5418 also provides a regulated output between 0V and the negative input voltage. SLM5418 works with a fixed operating frequency of 1MHz. The higher switching frequency devices allow the use of smaller capacitors for space-limited applications. An internal soft-start circuit effectively reduces the in-rush current during startup. The SLM5418 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.
