Dear team,
Customer use TPS7A10: input voltage 3.3V, output voltage 2.8V, load current 30mA. The output voltage could not reach 2.8V when Vin is 3.3V, only the Vin is 3.55V that Vout could reach 2.8V. Could you kindly help analysis this? Customer add two capacitor 1 0,1uF, 1 10uF in input and 4.7uF, 0.1uF in output. The bias was pullup to Vin through a resistor.
Thanks.
Best regards,
Sammi
