TCR3DM series

TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCR3DM series

300 mA CMOS Low Dropout Regulator with inrush current protection circuit

The TCR3DM 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 TCR3DM series are offered in the ultra small plastic mold package

DFN4/DFN4E (1.0 mm x 1.0 mm; t 0.58 mm). It has a low dropout voltage of

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

DFN4/DFN4E

μVrms (2.5 V output) and a load transient response of only ΔV_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

TCR3DM series, these devices are ideal for portable applications that require

high-density board assembly such as cellular phones.

Weight : 1.3 mg ( typ.)

Features



Low Dropout voltage

V_DO= 210 mV (typ.) at 2.5 V-output, I_OUT= 300 mA

V_DO= 270 mV (typ.) at 1.8 V-output, I_OUT= 300 mA

V_DO= 490 mV (typ.) at 1.2 V-output, I_OUT= 300 mA

Low output noise voltage



V_NO= 38 μV_rms(typ.) at 2.5 V-output, I_OUT= 10 mA, 10 Hz ≤ f ≤ 100 kHz



Fast load transient response (ΔV_OUT= ±80 mV (typ.) at I_OUT= 1 mA ⇔ 300 mA, C_OUT=1.0 μF)

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

Overcurrent protection

Over-temperature protection

Inrush current protection circuit

Auto-discharge

Pull down connection between CONTROL and GND

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