TCR4DG series

TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCR4DG series

420 mA CMOS Low Drop-Out Regulator with inrush current protection circuit

The TCR4DG 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 420 mA.

They feature over-current protection, over-temperature protection,

Inrush current protection circuit and Auto-discharge function.

The TCR4DG series are offered in the ultra small plastic mold

package WCSP4E (0.645 mm x 0.645 mm; t 0.43 mm (max)). It has

a low dropout voltage of 193 mV (3.3 V output, I_OUT= 420 mA) with

low output noise voltage of 38 μV_rms(2.5 V output) and a load

WCSP4E

Weight: 0.34 mg ( typ.)

transient response of only ⊿V_OUT= ±115 mV ( I_OUT= 1 mA ⇔ 420 mA, C_OUT=1.0 μF).

As small ceramic input and output capacitors can be used with the TCR4DG series, these devices are ideal for portable

applications that require high-density board assembly such as cellular phones.
