长晶CJ6211系列 CJ6211B12F 低压差稳压器

INTRODUCTION

The CJ6211 series are a group of positive voltage regulators manufactured by CMOS technologies with high ripple rejection, ultra low noise, low power consumption and low dropout voltage, which can prolong battery life in portable electronics. The CJ6211 series work with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications. The CJ6211 series consume less than 0.1μA in shutdown mode and have fast turn-on time less than 50μs.The series are very suitable for the battery-powered equipments, such as RF applicationsand other systems requiring a quiet voltage source.
