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, I_OUT= 300 mA) with low output noise voltage of 38 µV_rms

(2.5 V output) and a load transient response of only ⊿V_OUT= ±85

mV ( I_OUT= 1 mA⇔300 mA, C_OUT=1.0 µF).

Thus, the TCR3DF series are suitable for sensitive power supply

SMV

such as Analog and RF applications.

Weight :

SMV (SOT-25)(SC-74A) : 16 mg ( typ.)

Features

•

V_IN-V_OUT= 290 mV (typ.) at 1.8 V-output, I_OUT= 300 mA

V_IN-V_OUT= 510 mV (typ.) at 1.2 V-output, I_OUT= 300 mA

Low output noise voltage

•

100 kHz

V_NO= 38 µV_rms(typ.) at 2.5 V-output, I_OUT= 10 mA, 10 Hz

•

High ripple rejection ( R.R = 70 dB (typ.) at 2.5V-output, I_OUT= 10 mA, f =1kHz )

Over-current protection

Over-temperature protection

Inrush current protection circuit

Auto-discharge function

Pull down connection between CONTROL and GND

Ceramic capacitors can be used ( C_IN= 1.0µF, C_OUT=1.0 µF )
