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
750 µA at 100 mA output load. VOUT 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.
