TCR3EM series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR3EM series
300 mA CMOS Low Dropout Regulator
1. Description
The TCR3EM series are CMOS general-purpose single-output
voltage regulators with an on/off control input, featuring low dropout
voltage and fast load transient response.
These voltage regulators are available in fixed output voltages
between 0.8 V and 5.0 V and capable of driving up to 300 mA. They
feature Overcurrent protection, Thermal shutdown and Auto-
discharge.
The TCR3EM 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 160 mV (2.5 V output, I
= 150 mA). As small
OUT
ceramic input and output capacitors 1.0 µF can be used with the
TCR3EM series, these devices are ideal for portable applications
that require high-density board assembly such as cellular phones.
