Toshiba TCR3UM 300mA Low Dropout Regulators are CMOS general-purpose single-output voltage regulators with an on/off control input. The TCR3UM features an ultra-low quiescent bias current and low dropout voltage. The LDOs support fixed output voltages between 0.8V and 5.0V and can drive up to 300mA. Additionally, the devices provide over-current protection, thermal shutdown function, and auto-discharge. The Toshiba TCR3UM 300mA Low Dropout Regulators specifies a low dropout voltage of 196mV (3.3V output, IOUT = 300mA).
