general Description
The SP6265 dual, low dropout, linear regulators operate up to 5.5V input and deliver up to 50mA / 50mA output
current per regulator. It has a bypass pin option which allows users to decouple the bandgap reference for reducing
the output noise. Low dropout voltage and low quiescent current(70µA typ.) make them ideal for battery powered
applications. The SP6265 is available with a wide variety of standard voltage options and can be trimmed to .5%
accuracy. For protection purposes, SP6265 has a thermal shutdown feature to prevent device failure under the worst
operating conditions.
