1. Description

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/DFN4E (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.
