DC3158A

DC3158A evaluation board features the LT3041, a 20V, 1A, ultra-low noise and ultra-high power-supply rejection ratio (PSRR), low-dropout (LDO) linear regulator that incorporates voltage input-to-output control (VIOC) tracking. VIOC allows control of the upstream switching converter to maintain a constant voltage across the LT3041 and, therefore, minimizes power dissipation and maintains PSRR. The DC3158A operates over an input voltage range of 3.8V to 20V. The LT3041 delivers a maximum output current of 1A. In addition to featuring ultra-low noise and ultra-high PSRR, the regulator offers programmable power-good functionality and a programmable current limit. Current monitoring is also achieved by sensing the ILIM pin voltage.
