My customer is considering LDO.
They are looking for low fluctuate LDOs (1.8V ±5% w/ load transient).
These are conditions.
- Vin range : 2.8V to 4.2V (Li-ion battery)
- Vout : 1.8V
- Iout : 250mA(peak), typical Iout is less than 100mA
With 0A-> 250mA fluctuation, it is necessary to keep the drop within 5% from 1.8V.
Could you tell me LDO that TI recommend?
Competitor : Ricoh RP122

Load transient response
Iout : 0A to 250mA for 10usec (25mA/usec)
Cout : Currently 4.7uF//4.7uF are connected
Vout range : 1.8V +/-5.0%
