TCR3UF series

TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCR3UF series

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

1. Description

The TCR3UF series are CMOS process 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 Overcurrent

protection, thermal shutdown function and auto-discharge option.

The TCR3UF series is offered in general purpose package SMV (2.9 mm

x 2.8 mm; t 1.1 mm (typ.)) and has a low dropout voltage of 206 mV (3.3 V

output, I

= 300 mA). As small ceramic input and output capacitors 1 μF

OUT

can be used with the TCR3UF series, these devices are ideal for portable

applications that require high-density board assembly such as cellular

phones, IoT equipment and wearable devices.
