TCR3DMxxA series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR3DMxxA series
300 mA CMOS Low Drop-Out Regulator with inrush current protection circuit
1. Description
The TCR3DMxxA series are CMOS general-purpose single-output
voltage regulators with an on/off control input, featuring low dropout
voltage, low output noise voltage, fast load transient response 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
protection circuit and Auto-discharge.
The TCR3DMxxA series is offered in the ultra small plastic mold
package DFN4D (1.0 mm x 1.0 mm; t 0.37 mm (typ.)) and has a low
dropout voltage of 216 mV (2.5 V output, I
= 300 mA) with low
OUT
output noise voltage of 38 μVrms (2.5 V output). As small ceramic
input and output capacitors 1.0 μF can be used with the TCR3DMxxA
series, these devices are ideal for portable applications that require
high-density board assembly such as cellular phones.
