FEATURES
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. V
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.

... The SPX5205 provides access to the internal reference. A 10µF capacitor on the BYP pin will provide a significant reduction in output noise. This pin may be left unconnected if the output noise is not a major concern. The SPX5205 start-up speed is inversely proportional to the size of this capacitor. Applications requiring a slow ramp-up of output voltage should consider larger values of C ...
