Description
DC2246A 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) linear regulator with programmable current limit.
DC2246A operates over an input 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 of ILIM.
Built-in protection includes reverse battery protection, reverse current protection, internal current limit with foldback and thermal limit with hysteresis.
The LT3042 data sheet gives a complete description of the device, operation and applications information. The data sheet must be read in conjunction with this Demo Manual for demonstration circuit DC2246A. The LT3042EDD is assembled in a 10-lead (3mm x 3mm) plastic DFN package with an exposed pad on the bottom-side of the IC. Proper board layout is essential for maximum thermal performance and ultrahigh PSRR.
