TMI6030数据手册Tollsemi中文资料规格书

描述 Description

The TMI6030 is a 300mA,low-dropout(LDO)linear regulator with fast transient response and high PSRR.It offers high output accuracy,low dropout voltage and low quiescent current as well as fast start-up time.This regulator is based on a CMOS process.The TMI6030 is designed to work with low-ESR ceramic capacitors,reducing the amount of the PCB area necessary for power applications.Only a 1μF ceramic output capacitor can make the device stable over the whole load range current(0mA to 300mA).Theoutputvoltage ofTMI6030 can be set by an external resistors divider.When the FB pin is connected to an external resistors divider,its output can be adjusted from 1.2V to 5V.As to fixed output voltage version,a ceramic capacitor on BP pin could be used to improve output noise performance and PSRR performance.Other key features include over-current protection and thermal shutdown.The TMI6030 is packaged in DFN4L1×1 and SOT23-5 packages.
