TCR3UG series

Ultra low quiescent current, Fast Load Transient 300 mA CMOS Low Dropout Regulator in ultra

small package

1. Description

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 function and Auto-discharge option.

The TCR3UG series is offered in the ultra small plastic mold package

WCSP4F (0.645 mm x 0.645 mm (typ.); t 0.33 mm (max)) and has a low

dropout voltage of 155 mV (3.3 V output, IOUT = 300 mA). As small ceramic

input and output capacitors 1

μF can be used with the TCR3UG series, these

devices are ideal for portable applications that require high-density board

assembly

such as cellular phones, IoT equipment and wearable devices.

2. Applications

Power IC developed for portable applications, IoT equipment and wearable devices
