TCR3UG series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR3UG series Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Dropout Regulator in ultra small package 1. Description The TCR3UG 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 option. The TCR3UG series is offered in the ultra small plastic mold package WCSP4F WCSP4F (0.645 mm x 0.645 mm (typ.) t 0.33 mm (max)) and has a low Weight: 0.26 mg (typ.) dropout voltage of 155 mV (3.3 V output, IOUT = 300 mA). As small ceramic input and output capacitors 1 F can be used with the TCR3UG series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones, IoT equipment and wearable devices. 2.
