TLV62084A: Reducing Input Capacitance

Part Number: TLV62084A


My customer is testing TLV62084A and they have a 10uF capacitor on the input as recommended, but are wondering if this value can be reduced.  They are seeing some in-rush current that is higher than they would like, and reducing this input capacitance shows a reduction in that in-rush current.  Can a lower Cin be used without causing this device to go unstable or out of regulation?

Vin = 2.7 to 5.5V

Vout = 1.85V

Iout = <1mA in idle, and <30mA average in run mode
