Digital Potentiometers

Digital Potentiometers(AD5204) The digital Potentiometers made by analog devices (AD5204) has 255 positions can be adjusted by the microcomputer that can receive commands from the computer. This is a great way for analog circuitry to have digital control. This is a chip with 4 digitally controlled POTs and the pots can be daisy chained to have multiple chips controled by a single SPI interface.


Voltage Regulators

Linear Regulators

  • LT1528 LT1528 High current, Variable Voltage Regulator
  • TPS V-Reg TPS V-Regs These are 3.3V and 5V LDO, Low-Noise Voltage Regulators. Very small SOT-23 SMD package. 150mA max current. Best used in battery applications.
  • Main-LM7805.jpg Basic Voltage Regulators Variable voltage regulators, set output regulators, we give you the whole breakdown. Perfect for use with an external wall-wart power supply.
