LT3045 LT3042 Single Power Linear Regulator Low Noise Ripple Radio Frequency RF Microwave Power Supply 3.3V 5V 12V 15V Audio

LT3042 / LT3045 Ultra‑Low Noise LDO Voltage Regulator Module – High PSRR, RF & Microwave Power SupplyProduct Description:This module is based on the LT3042 and LT3045ultra‑low noise linear regulators, designed specifically for RF, microwave, and other noise‑sensitive applications. Both versions offer a wide input range (1.8V–20V), adjustable output from 0V to 15V, and exceptional ripple rejection. The LT3045 provides up to 500mA output current, while the LT3042 delivers 200mA. With extremely low RMS noise and high PSRR, these modules are ideal for powering phase‑locked loops (PLLs), VCOs, ADCs, DACs, and precision instrumentation. XH2.54‑2PIN input/output connectors(Cable not included or Type‑C input (5V only). Output voltage can be adjusted via potentiometer or fixed resistors.Specifications:ParameterLT3042LT3045Input Voltage Range1.8V – 20V1.8V – 20VOutput Voltage Range0V – 15V (adjustable)0V – 15V (adjustable)Max Output Current200mA500mAMinimum Dropout Voltage350mV260mVRMS Noise (PSRR @ 1MHz)79dB79dBInput ConnectorXH2.54‑2PIN or Type‑C (5V only for Type‑C)Cable not includedOutput ConnectorXH2.54‑2PINCable not includedDimensions2.5 × 3.5 cmSameKey Features:Ultra‑low RMS noise and high PSRR – ideal for RF and analog circuitsAdjustable output voltage (potentiometer or fixed resistors)Wide input and output voltage flexibilityCompact size for easy integrationType‑C or XH2.54 input options Cable not includedApplications:RF and microwave circuits (PLL, VCO, mixers, LNAs)High‑precision ADC / DAC reference suppliesLow‑noise instrumentation and medical devicesAudio and communication equipmentBattery‑powered portable devicesLaboratory power supply building blocks
