TCR3DF series
300 mA
CMOS Low Drop-Out Regulator with inrush current protection circuit
The TCR3DF series are
CMOS general-purpose single-output
voltage regulators with an on/off control input, featuring low dropout
voltage, low output noise
voltage and low inrush current.
These
voltage regulators are available in fixed output
voltages between 1.0 V and 4.5 V and capable of driving up to 300 mA. They feature over-current protection, over-temperature protection, Inrush current protection circuit and Auto-discharge function.
The TCR3DF series has a low dropout
voltage of 230 mV (2.5 V output, IOUT = 300 mA) with low output noise
voltage of 38 µVrms (2.5 V output) and a load transient response of only ⊿VOUT = ±85 mV ( IOUT = 1 mA⇔300 mA, COUT =1.0 µF).
Thus, the TCR3DF series are suitable for sensitive power supply such as Analog and RF applications.
