PRODUCT DESCRIPTION
The SPX5205 is an excellent choice for use in battery-powered applications, and where power conservation is desired. Such as:
cellular/ cordless telephones, radio control systems, and portable computers.
This device is a positive voltage regulator with very low dropout voltage and low output noise. It uses very little quiescent current of

tolerance is less than 1% with a compensated temperature coefficient. Many fixed output
voltages, as listed below, or an adjustable version are available in a small 5-pin SOT-23 package.
Other key features include: Zero off-mode current, protection against reversed battery, thermal and current limiting.
