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, 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.

Note:
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
