The 50 mA output ceiling suits it for powering a small MCU, an op-amp rail, or a reference buffer — not a main power bus. Programmable output via a logic pin selects 1.8 V or 1.9 V — useful when the same PCB must serve two core-voltage targets without a resistor swap. ## Active production and compliance Supplied in tubes, the 10-uMAX/uSOP footprint matches the standard 10-MSOP land pattern; the 0.118-inch body width fits tight channel spacing on a mixed-signal board.","metaTitle":"MAX1730EUB+ Analog Devices Charge Pump, 50mA, 10-uMAX","metaDescription":"MAX1730EUB+ step-down charge pump from Analog Devices, 2.7-5.5V input, programmable 1.8/1.9V output at 50mA.
