TCR8BM24A
TCR8BM series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR8BM series
800 mA CMOS Ultra Low Dropout Regulator
The TCR8BM series are CMOS single-output voltage regulators with an
on/off control input, featuring ultra low dropout voltage, high PSRR, low
inrush current and fast load transient response.
A differentiating feature is the use of a secondary bias rail as a reference
voltage that allows ultra low dropout of 170 mV (Typ.) at IOUT = 800 mA ( 1.1
V output, VBIAS = 3.3 V ).
These voltage regulators are available in fixed output voltages between 0.8
V and 3.6 V, and capable of driving up to 800 mA. Other features include
overcurrent protection, thermal shutdown, and Auto-discharge.
The TCR8BM series are offered in the ultra small plastic mold package
DFN5B (1.2 mm x 1.2 mm; t 0.38 mm).
As small ceramic input and output capacitors can be used with the
TCR8BM 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).

Note 2:
Do not operate at or near the maximum ratings of operating ranges for extended periods of time. Exposure to
such conditions may adversely impact product reliability and results in failures not covered by warranty.
Maximum operating ranges output current specification defined as lifetime average junction temperature of
+45°C where max rated DC current = lifetime average current to avoid electro migration.
