TCR3DF10,LM(CT

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.
