TCR5SC18FE½TCR5SC36FE
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR5SC18FE½TCR5SC36FE
150 mA CMOS Low-Dropout Regulator (Point regulator)
The TCR5SC18FE to TCR5SC36FE are CMOS general-purpose
single-output voltage regulators with an on/off control input, featuring
low dropout voltage and low quiescent bias current. The
TCR5SC18FE to TCR5SC36FE can be enabled and disabled via
the CONTROL pin.
These voltage regulators are available in fixed output voltages
between 1.8 V and 3.6 V in 0.1-V steps and capable of driving up to
150 mA. They feature overcurrent protection.
The TCR5SC18FE to TCR5SC36FE are offered in the compact
ESV (SOT-553) and allow the use of small ceramic input and output
capacitors. Thus, 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).

The figure above shows the recommended configuration for using a Low-Dropout regulator. Insert a capacitor at
Vout and Vin pins for stable input/output operation. (Ceramic capacitors can be used)
If the control function is not used, Toshiba recommend that the control pin is connected to the V
