TCR2DG series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR2DG series
Low Noise 200 mA CMOS Low Drop-Out Regulator in ultra small package
The TCR2DG series are CMOS general-purpose single-output
voltage regulators with an on/off control input, featuring low dropout
voltage, low quiescent bias current and fast load transient response.
These voltage regulators are available in fixed output voltages
between 1.2 V and 3.6 V and capable of driving up to 200 mA. They
feature overcurrent protection and thermal shut down function.
The TCR2DG series is offered in the ultra small package WCSP4
( 0.79 mm x 0.79 mm x 0.5 mm). It has a low dropout voltage of 75
mV ( 2.5 V output, IOUT = 100 mA) with low output noise voltage of 18
μVrms (2.5 V output) and a load transient response of only
VOUT = ±65 mV ( IOUT = 1 mA150 mA, COUT =1.0 μF).
As small ceramic input and output capacitors can be used with the
Weight : 0.7 mg (typ.)
WCSP4
TCR2DG series, these devices are ideal for portable applications that require high-density board assembly such as
cellular phones.
Features
Low Drop-out Voltage ( VIN-VOUT = 75 mV (typ.) at 2.5 V-output, IOUT = 100 mA )
Low quiescent bias current ( IB = 45 μA (typ.) at IOUT = 0 mA )
Low stand-by current ( IB(OFF) = 0.1 μA (typ.) at Stand-by mode )

Attention in Use
Output Capacitors
Ceramic capacitors can be used for these devices. However, because of the type of the capacitors, there might be
unexpected thermal features. Please consider application condition for selecting capacitors. And Toshiba
recommend the ESR of ceramic capacitor is under 10 .
Mounting
The long distance between IC and output capacitor might affect phase assurance by impedance in wire and inductor.
For stable power supply, output capacitor need to mount near IC as much as possible. Also GND pattern need to
be large and make the wire impedance small as possible.
Permissible Loss
Please have enough design patterns for expected maximum permissible loss. And under consideration of
surrounding temperature, input voltage, and output current etc, we recommend proper dissipation ratings for
maximum permissible loss; in general maximum dissipation rating is 70 to 80 percent.
Over current Protection and Thermal shut down function
Over current protection and Thermal shut down function are designed in these products, but these does not assure
for the suppression of uprising device operation.
In use of these products, please read through and understand dissipation idea for absolute maximum ratings from
the above mention or our ‘Semiconductor Reliability Handbook’. Then use these products under absolute maximum
ratings in any condition. Furthermore, Toshiba recommend inserting failsafe system into the design.
