TCR3UM series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR3UM series
Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Dropout Regulator in ultra
small package
1. Description
The TCR3UM series are CMOS general-purpose single-output voltage
regulators with an on/off control input, featuring ultra low quiescent bias
current and low dropout voltage.
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 Over-current
protection, Thermal Shutdown function and Auto-discharge.
The TCR3UM series is offered in the ultra small plastic mold package
DFN4/DFN4E (1.0 mm x 1.0 mm; t 0.60 mm (max)) and has a low dropout
voltage of 196 mV (3.3 V output, I
OUT
= 300 mA). As small ceramic input and
output capacitors 1 μF can be used with the TCR3UM series, these devices
are ideal for portable applications that require high-density board assembly
such as cellular phones, IoT equipment and wearable devices.
