Dual Low-Dropout CMOS Voltage Regulator

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 S

P6265 is available with a wide variety of standard voltage options and can be trimmed to .5%

accuracy. For protection purpose

s, SP6265 has a thermal shutdown feature to prevent device failure under the “worst”

operating conditions.
