Description

DC2246B is a linear regulator featuring the LT®3042EDD, which is a 200mA, ultralow noise, and ultrahigh power supply rejection ratio (PSRR) RF low dropout (LDO) regulator with programmable current limit.

Features

DC2246B operates over an input voltage range of 3.8Vto 20V. The LT3042 has a maximum output current of200mA. It features ultralownoise (0.8µVRMS from 10Hz to 100kHz) and very high PSRR (79dB at 1MHz). The power good feedback (PGFB) pin voltage is programmable for powergoodthreshold. Acurrentlimitfunction isprovided. Current monitoring is also achievable by sensing the voltage on the ILIM pin.
