The LT3402 provides power supply ripple rejection (PSRR), spot noise of only 2nV/√Hz at 10kHz and 0.8-microvolsts of integrated output noise across 10Hz to 100kHz bandwidth. Low frequency PSRR exceeds 90dB out to 10kHz and high frequency PSRR exceeds 75dB out to 3MHz, quieting noisy or high ripple input supplies.

The LT3042 delivers up to 200mA output current with a 350mV dropout voltage at full load, across a wide 1.8V to 20V input voltage range. Output voltage range is 0V to 15V and output voltage tolerance is ±2 percent over line, load and temperature.

The device is suitable for providing regulated voltage to PLLs, VCOs, mixers and LNAs, instrumentation, data converters, medical applications such as imaging and diagnostics, precision power supplies and as a post regulator for switching supplies.
