TCR2EE series
200 mA CMOS Low Drop-Out Regulator with Fast Load Transient Response
The TCR2EF and TCR2EF series are CMOS single-output voltage
regulators with an on/off control input, featuring low dropout voltage,
low output noise voltage and fast load transient response.
These voltage regulators are available in fixed output voltages
between 1.0 V and 5.0 V and capable of driving up to 200 mA. They
feature overcurrent protection, an Auto-discharge function.
The TCR2EF and TCR2EE series has a low dropout voltage of
180 mV ( 2.5 V output, I
OUT
= 150 mA) with low output noise voltage
of 35
μV
rms
(2.5 V output) and a load transient response of only
⊿
V
OUT
=
±60
mV ( I
OUT
= 1 mA⇔150 mA, C
OUT
=1.0
μF).
Thus, the TCR2EF and TCR2EE series are suitable for sensitive
power supply such as Analog and RF applications.

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).
