TCR2EN series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR2EN series
200 mA CMOS Low Drop-Out Regulator in ultra small package
The TCR2EN 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 1.0 V and 3.6 V and capable of driving up to 200 mA. They
feature overcurrent protection and an Auto-discharge function.
The TCR2EN series is offered in the ultra small plastic mold
package SDFN4 ( 0.8 mm x 0.8 mm x 0.38 mm). It has a low
dropout voltage of 160 mV ( 2.5 V output, I
OUT
= 150 mA) with low
output noise voltage of 35
μδV
rms
(2.5 V output) and a load transient
response of only
⊿V
OUT
=
±55
mV ( I
OUT
= 1 mA⇔150 mA, C
OUT
=1.0
μF).
As small ceramic input and output capacitors can be used with the
TCR2EN series, these devices are ideal for portable applications
that require high-density board assembly such as cellular phones.

Note:
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).
