TCR3DF18,LM(CT

The TCR3DF series are CMOS general-purpose single-output regulators with ON/OFF control input, featuring low dropout voltage, low output noise voltage, and low inrush current. These regulators provide fixed output voltages between 1.0 V and 4.5 V, capable of driving up to 300 mA. They incorporate overcurrent protection, overtemperature protection, inrush current protection circuitry, and auto-discharge functionality. The series features a low dropout voltage of 230 mV (2.5 V output, IOUT = 300 mA), low output noise voltage of 38 μVrms (2.5 V output), and load transient response of only ⊿VOUT = ±85 mV (IOUT = 1 mA⇔300 mA, COUT = 1.0 μF). As a result, the TCR3DF series is well-suited for sensitive power supply applications such as analog and RF circuits.
