TCR3UG32A Fast Load Transient 300mA CMOS Low Drop-Out Regulator

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 functi.

Features

• Ultra small package WCSP4F (0.645 mm x 0.645 mm (typ.); t 0.33 mm (max)).
