The HMC1060LP3E is a BiCMOS ultra low noise quad-output linear voltage regulator targeted at high performance applications requiring superb power supply isolation.Maximum 500 mA of current, distributed between four independent outputs, enable the HMC1060LP3E to supply all of the power needs of Hittite's Wideband PLL with Integrated VCO products, such as the HMC830LP6GE.Although targeted at Hittite's Wideband PLLs with Integrated VCO products, the HMC1060LP3E makes an excellent general purpose regulator that supports adjustable output voltages ranging anywhere from 1.8V to 5.2V.An Integrated PTAT (Proportional To Absolute Temperature) feature enabled via an external pin, allows the HMC1060LP3E to scale the supply voltage with temperature in order to maximize phase noise and output power performance of Hittite's Wideband with Integrated VCO products, as well as other devices powered by the HMC1060LP3E.Integrated thermal protection disables the outputs of the HMC1060LP3E at extreme temperatures, until the device cools down, making the HMC1060LP3E a robust device capable of dealing with temporary and unforeseen scenarios including momentary short circuits and extreme temperatures.External Enable input provides a convenient way to power on or off all of the devices supplied by the HMC1060LP3E.The HMC1060LP3E is housed in a 3 × 3 mm QFN SMT package.APPLICATIONSUltra Low Noise Frequency Generation (PLLs, VCOs, PLLs with Integrated VCOs)RF & Mixed-Signal Supply
