TCR3DF series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR3DF series 300 m A 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 m A. 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 m V (2.5 V output, IOUT = 300 m A) with low output noise voltage of 38 µVrms (2.5 V output) and a load transient response of only ⊿VOUT = ±85 m V ( IOUT = 1 m A⇔300 m A, COUT =1.0 µF). Thus, the TCR3DF series are suitable for sensitive power supply such as Analog and RF applications.
