TCR3RM series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR3RM series
Ultra high Ripple rejection ratio, 300 mA CMOS Low Dropout Regulator in ultra small package
Description
The TCR3RM series are CMOS general-purpose single-output
voltage regulators with an on/off control input, featuring low output
voltage noise and ultra-high Ripple rejection ratio.
These voltage regulators are available in fixed output voltages
between 0.9 V and 4.5 V and capable of driving up to 300 mA.
They feature Overcurrent protection, Thermal shutdown and Auto-
discharge.
The TCR3RM series is offered in the ultra small plastic mold
package DFN4C/DFN4F (1.0 mm x 1.0 mm; t 0.38 mm (Typ.)) and
has a high ripple rejection ratio of 100 dB (f = 1 kHz, 2.8 V output).
DFN4C/DFN4F
As small ceramic input and output capacitors 1μF can be used with the TCR3RM series, these devices are
ideal for portable applications that require high-density board assembly such as cellular phones.
