TCR3DM series
300 mA
CMOS Low Drop-Out 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 (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).

Weight : 1.3 mg ( typ.)
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.
