Hittite Microwave Corp. has introduced the product line, DC Power Conditioning, ideal for low noise voltage regulation in automotive telematics, cellular/4G, WiMAX/4G, military and test equipment applications.
The HMC860LP3E is a low noise, high PSRR (Power Supply Rejection Ratio), quad output linear voltage regulator. It features a low noise band gap reference externally decoupled for best in-close noise performance. High PSRR in the 0.1 to 10 MHz range provides excellent rejection of preceding switching regulator noise. The HMC860LP3E provides four voltage outputs that are adjustable from 2.5 to 5.2 V, and are ideal for conditioning the DC power supply to many low noise frequency generation subsystems, including Hittite’s broad line of PLLs with integrated VCOs. Each of the four voltage outputs can be adjusted higher or lower than the default value by using one external resistor, or each output can be set to 5 V by grounding the appropriate pin. The HMC860LP3E regulator can also be powered down via its TTL-compatible enable input to consume < 1 uA.
The HMC860LP3E is ideal for conditioning the DC supply voltage to Hittite’s broad line of high performance frequency generation products. The HMC860LP3E low noise, high PSRR, quad output linear voltage regulator is housed in a compact and RoHS compliant 3x3 mm QFN SMT package.
Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order.
