SPX5205 General 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 A 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.
