TCR3DM series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
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).

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.

Note:
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rat.
