DC2246B

DC2246B is a LT3042EDD 20V, 200mA, ultra-low Noise ultra-high PSRR RF LDO regulator demonstration board. DC2246B is a linear regulator featuring the LT®3042EDD which is a 200mA, ultra-low noise and ultra-high power supply rejection ratio (PSRR) RF low dropout (LDO) regulator with programmable current limit. DC2246B operates over an input voltage range of 3.8V to 20V. The LT3042 has a maximum output current of 200mA. It features ultralow noise (0.8µVRMS from 10Hz to 100KHz) and very high PSRR (79dB at 1MHz). The power good feedback (PGFB) pin voltage is programmable for power good threshold. A current limit function is provided. Current monitoring is also achievable by sensing the voltage on the ILIM pin.
