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?
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
