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

μVrms (2.5 V output) and a load transient response of only ΔVOUT = ±80 mV
( IOUT = 1 mA⇔300 mA, COUT =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.
