The MCP1252-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 120 mA 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. The MCP1252 operates at a switching frequency of 650 kHZ and features a power-good pin that monitors out-of-regulation conditions.
