TCR3UM series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR3UM series Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Drop-Out Regulator in ultra small package 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 (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, IOUT = 300 mA). As small ceramic input and output BOTTOM VIEW ILLUSTRATION capacitors 1 F can be used with the TCR3UM series, these devices are DFN4 ideal for portable applications that require high-density board assembly such Weight: 1.3 mg (typ.) as cellular phones, IoT equipment and wearable devices. Applications Power IC developed for portable applications, IoT equipment and wearable devices Features Ultra small package DFN4 (1.0 mm x 1.0 mm t 0.60 mm (max)).
