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.
