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 )
Low output noise voltage
VNO = 22 μVrms (typ.) at 3.0 V-output, IOUT = 10 mA, 10 Hz < f < 100 kHz
VNO = 18 μVrms (typ.) at 2.5 V-output, IOUT = 10 mA, 10 Hz < f < 100 kHz
VNO = 14 μVrms (typ.) at 1.2 V-output, IOUT = 10 mA, 10 Hz < f < 100 kHz
High ripple rejection ratio
R.R = 75 dB (typ.) at 2.5 V-output, IOUT = 10 mA, f =1kHz
R.R = 62 dB (typ.) at 2.5 V-output, IOUT = 10 mA, f =10kHz
R.R = 50 dB (typ.) at 2.5 V-output, IOUT = 10 mA, f =100kHz
Fast load transient response (VOUT = ±65 mV (typ.) at IOUT = 1mA 150 mA, COUT =1.0 μF )
Output voltage accuracy ±1.0 %
Over current protection
Thermal shut down function
Built-in inrush current reduction circuit
Pull down connection between CONTROL and GND
Ceramic capacitors can be used ( CIN = 0.47μF, COUT =1.0 μF )

Note:
Note1:
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Rating at mounting on a board
Glass epoxy(FR4) board dimension: 40mm x 40mm x 1.8mm, both sides of board
Metal pattern ratio: a surface approximately 50%, the reverse side approximately 50%
Through hole: diameter 0.5mm x 28
