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.
