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.

The 723 Voltage Regulator 		Precision Voltage Regulator. Can be used as fixed or floating, variable, linear or switching.

NOTE: Only the DIP-14 version (image) has the Vz pin, which is used for negative regulators. The Metal Can and the Flat-Pack do not have enough pins so exclude the Vz.
