Toshiba TCR3UM LDO Voltage Regulators

Author : Toshiba semiconductors Published Time : 2018-08-20
Toshiba TCR3UM LDO Voltage Regulators 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 0.8V and 5.0V and capable of driving up to 300mA. They feature Over-current protection, Thermal Shutdown function and Auto-discharge. The TCR3UM series is offered in the ultra small plastic mold package DFN4 (1.0mm x 1.0mm; t 0.60mm (max)) and has a low dropout voltage of 196 mV (3.3V output, IOUT = 300 mA). As small ceramic input and output capacitors 1 μF can be used with the TCR3UM series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones, IoT equipment and wearable devices.
