General Description
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
1.8 V to 5.2 V.
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 3x3 mm QFN SMT
package.
