Large current, low dropout, low output ripple, small size LDO selection

Large current, low dropout, low output ripple, small size LDO selection

Output 1.8v 1.5A, Power the CMOS sensor,The input voltage is 2.0-3.3V,Is there an LDO that is small in size, meets the conditions, and generates a small amount of heat?  Can TPS7A7002 satisfy? Is this power supply an LDO? Is the output ripple large?

Johnsin Tao:

Hi可以用这个芯片,主要就是注意当输入电压较高时,例如3.3V输如,功耗高达2.25W, 那么散热设计就很重要了。

回复 Johnsin Tao:

I want to use 2.0V as the input and 1.8V as the output so that the LDO heats up very little,In this case, the LDO must support ultra-low dropout,vin-vout=0.2V,So it’s not very hot.TPS7A7300, Can you see that the TPS7A7300 chip supports 0.2V input and output voltage difference?I did not see the specific introduction about this in the data sheet . This chip should dissipate heat better than TPS7A7002
