Low Voltage Power Supplies

Robert Dobkin - Chief Technical Officer Jun 9th 2016
In this video, Linear Technology Co-founder and CTO Bob Dobkin discusses low voltage power supplies less than half a volt. Most of today's power supplies have a reference of 0.6 volts, which means the output voltage must be greater than 0.6 volts. Several years ago, Linear Technology pioneered a new type of current source reference ...

Ultralow Noise and Ultrahigh PSRR

Amit Patel Jun 17th 2015
When it comes to powering noise-sensitive analog/RF applications, low dropout (LDO) linear regulators are generally preferred over their switching counterparts. Low noise LDOs power a wide range of analog/RF designs, including frequency synthesizers (PLLs/VCOs), RF mixers and modulators, high speed and high resolution data converters ...

1.5A LDO+ Regulator Monitors Current & Temperature

Robert Dobkin - Chief Technical Officer Feb 5th 2014
LDO+ regulators do more than just regulate. They include monitor and control functions as well as regulation. The LT3081 has a wide safe area, allowing operation with high currents at high input-output differentials. Output voltage is adjustable from from 0 to 37 volts and it withstands reverse voltage. In addition to regulating, ...

Minimizing Switching Regulator Residue in Linear Regulator Outputs

Jim Williams - Applications Guru Mar 21st 2011
Linear regulators are commonly employed to post-regulate switching regulator outputs. Benefits include improved stability, accuracy, transient response and lowered output impedance. Ideally, these performance gains would be accompanied by markedly reduced switching regulator generated ripple and spikes. In practice, all linear ...

Introducing the LT3070 Point-of-Load Regulator for FPGA & Server Backplanes

Kelly Consoer - Design Engineer Jan 4th 2011
Modern FPGAs and servers operating at low voltages are sensitive to subtle supply drops. The droop may result from a combination of excess regulator noise, insufficient bandwidth in the supply regulator, excess ESR & ESL in the decoupling components, or distributed inductance in the power distribution. To abate the risk of ...

Directly Parallel This High Power Density Linear Regulator - LT3080

Robert Dobkin - Chief Technical Officer Sep 15th 2008
The LT3080 is a new architecture for linear regulators. It provides better regulation, a simple output adjustment with a single resistor where the output can be adjusted down to zero. Also, this architecture allows easy paralleling of regulators for “no heatsink” operation in an all surface mount applications. The LT3080 ...
