TCR3UM45A Datasheet CMOS Low Drop-Out Regulator

Manufacturer: Toshiba

Overview: TCR3UM series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR3UM series Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Drop-Out Regulator in ultra small package The TCR3UM 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. The TCR3UM series is offered in the ultra small plastic mold package DFN4 (1.0 mm x 1.0 mm; t 0.60 mm (max)) and has a low dropout voltage of 196 mV (3.3 V 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.
