Voltage Regulators

Linear Regulators
LT1528	High current, Variable Voltage Regulator
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.
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.
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.

-[http://www.linxtechnologies.com/ Linx Technologies] makes several low power RF transmitter/receiver chips. Their range is around 500' - 1000'. They are geared for one way communication only, like keyless entry systems. They also make several serial encoding chips that make the wireless communication more secure/crack proof. Their latest chip, the HS series, is based upon the SkipJack algorithm developed by the NSA.
