TOSHIBA TCR3UG08A,LF

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 (0.645 mm×0.645 mm (typ.); t 0.33 mm (max)) and has a low dropout voltage of 155 mV (3.3 V output, lout = 300 mA). As small ceramic input and output capacitors 1 μF 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. Weight: 0.26 mg (typ.)
