TCR3UF series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR3UF series Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Dropout Regulator Description The TCR3UF series are CMOS process 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 Overcurrent protection, thermal shutdown function and auto-discharge option. The TCR3UF series is offered in general purpose package SMV (2.9 mm x 2.8 mm t 1.1 mm (typ)) and has a low dropout voltage of 206 mV (3.3 V output, IOUT = 300 mA). As small ceramic input and output capacitors 1 F can be used with the TCR3UF series, these devices are ideal for portable SMV applications that require high-density board assembly such as cellular Weight: phones, IoT equipment and wearable devices.
