LR6302

INTRODUCTION

The LR6302 series are a group of positive

voltage regulators manufactured by CMOS

technologies with low power consumption

and low dropout voltage, which provide

large output currents even when the

difference of the input-output voltage is

small. The LR6302 series can deliver

300mA output current and allow an input

voltage as high as 18V. The series are

very

suitable

for

the

battery-powered

equipments, such as RF applications and

other systems requiring a quiet voltage

source.
