TCR3DF28 Overview
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. Thus, the TCR3DF series are suitable for sensitive power supply such as Analog and RF applications. • Low output noise voltage VNO = 38 µVrms (typ.) at 2.5 V-output, IOUT = 10 mA, 10 Hz <= f <= 100 kHz
