The SGM2057 is a negative output charge pump which has an inside adjustable regulator. The input voltage range is from 2.3V to 5.5V and the unregulated output equals to -VIN. For the regulated output of the SGM2057, it equals to -VCTL and the range is from 0V to -VIN.

The inrush current of the SGM2057 can be decreased by the internal soft-start circuit. For application case, four ceramic capacitors and no inductor are required, and it can be used for supplying optical modules, bias of RF amplifiers and sensors.

The SGM2057 is available in a Green TQFN-1.8×1.4-10L package. It operates over an operating temperature range of -40 to +125.
