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, 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.
