What PIC MCP 1253-ADJ chip is used for?

Thank you

The MCP1253-ADJ is an inductorless, positive regulating, low noise charge pump DC-to-DC converter. It has an adjustable output of either 1.5V to 5.0V and can deliver 120mA of load current at the desired regulated output voltage. Since the device incorporates an automatic buck/boost feature, it will maintain the regulated output voltage whether the input voltage is above or below the output voltage

It it one kind of chip similar like other else chip and can be programmed?

 

[Kripton2035]

it is "programmable" with 2 resistors you put between the vout and the fb pin
then you have VOUT = 1.21V (1 + R1/R2)
see the typical applcation schematic in the datasheet.
