Hi Team

could TPS7A02 support Vin 2.1 and Vout 1.8 when I out=200mA?

or do you have any recommendation support such low drop out?

Hi Brian,

Per the EC Table, the dropout for 1.8 Vout for Iout = 200 mA is 400-450 mV depending on the junction temperature. VIN = 2.1V would put the LDO in dropout since Vin - Vout would be lesser than 400 mV.

TPS7A11 (TPS7A11 500-mA, Low VIN, Low VOUT, Ultra-Low Dropout Regulator datasheet (Rev. B)) Is a very good device for this condition.

Regards

Ishaan
