TCR3DG series

TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCR3DG series

300 mA CMOS Low Dropout Regulator with inrush current protection circuit

Description

The TCR3DG 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 overcurrent protection, thermal shutdown, Inrush current

reduction and Auto-discharge.

The TCR3DG series are offered in the ultra small package WCSP4E

(0.645 mm x 0.645 mm; t 0.40 mm). It has a low dropout voltage of 160 mV

(3.2 V output, I_OUT= 300 mA) with low output noise voltage of 38 μV_rms(2.5

WCSP4E

Weight : 0.34 mg (Typ.)

V output) and a load transient response of only ⊿V_OUT= ±80 mV (I_OUT

1 mA⇔300 mA, C_OUT= 1.0 μF).

As small ceramic input and output capacitors can be used with the TCR3DG series, these devices are ideal for portable

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

Applications

Power IC developed for portable applications, IoT equipment and wearable devices
