TCR5SB15A½TCR5SB50A
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR5SB15A½TCR5SB50A
150 mA CMOS Low-Dropout Regulator (Point Regulator)
The TCR5SB15A to TCR5SB50A are CMOS general-purpose
single-output voltage regulators with an on/off control input, featuring
low dropout voltage and low quiescent bias current. The
TCR5SB15A to TCR5SB50A can be enabled and disabled via the
CONTROL pin.
These voltage regulators are available in fixed output voltages
between 1.5 V and 5.0 V in 0.1-V steps and capable of driving up to
150 mA. They feature overcurrent protection.
The TCR5SB15A to TCR5SB50A are offered in the compact SMV
(SOT23-5) (SC-74A) 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).
