Maximum Output Current: more than 250mA
The FT510xx series are precise, extra low power
consumption, positive voltage regulators with a
significantly small dropout voltage. Each device
contains a current limiter circuit, a PMOS power
transistor, a precision reference voltage and an error
amplifier circuit.
Dropout Voltage: 160 mV
(Vout=3.0V)
