Toshiba Electronics Europe TCR3RMxxx

The TCR3RM series is constructed in a plastic DFN4C package measuring 1.00mmx1.00mmx0.38 mm and comprises 32 product variants with fixed single output voltages in the range 0.9 V_DC to 4.5 V_DC.

Unlike other LDO regulators where the ripple rejection ratio usually drops 20dB every 10-fold increase in frequency, the TCR3RM falls significantly less. The rejection ratio at 1MHz and a 2.8V output is 68dB.

With a maximum output current of 300mA, the TCR3RM series employs a bandgap circuit, a low pass filter, and a low-noise, high speed operational amplifier to provide the regulator with excellent ripple rejection and output noise specifications.
