TCR5SB15U~TCR5SB50U
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR5SB15U~TCR5SB50U
200-mA CMOS Low-Dropout Regulators (Point Regulators)
The TCR5SB15U to TCR5SB50U are CMOS general-purpose
single-output voltage regulators with an on/off control input, featuring
low dropout voltage and low quiescent bias current. The
TCR5SB15U to TCR5SB50U 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
200 mA. They feature overcurrent protection.
The TCR5SB15U to TCR5SB50U are offered in the compact UFV
package measuring 2.0 x 2.1 x 0.7 mm 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).
