TCR3DF series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic 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, I = 300 mA) with low output noise voltage of 38 V OUT rms (2.5 V output) and a load transient response of only V = 85 OUT mV ( I = 1 mA300 mA, C =1.0 F). OUT OUT SMV Thus, the TCR3DF series are suitable for sensitive power supply such as Analog and RF applications. Weight : SMV (SOT-25)(SC-74A) : 16 mg ( typ.)
