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).

Attention in Use
●
Capacitors(Output, Input, and Bias Capacitor)
Ceramic capacitors can be used for these devices. However, because of the type of the capacitors, there might be unexpected
thermal features. Please consider application condition for selecting capacitors. For stable operation, please use over 1.0 μF
input capacitor, 0.1 μF bias capacitor and 2.2 μF output ceramic capacitor.
●
Recommending for Control Pin Operation
This device is optimized to operate the best performance when turn on and off with control pin. Especially the rush current
and bias current can be suppressed by using control pin after applying V and V
.
IN BIAS
TCR8BMxxA products have V under voltage lockout function, bias current is suppressed at low V
IN IN
even when V and
BIAS
V
are applied.
CT
●
Mounting
The long distance between IC and output capacitor might affect phase compensation by impedance in wire and inductor. For
stable power supply, output capacitor need to mount near IC as much as possible. Also V and GND pattern need to be
IN
large and make the wire impedance small as possible.
●
●
Permissible Loss
Please have enough design patterns for expected maximum permissible loss. And under consideration of ambient
temperature, input voltage, and output current etc, we recommend proper dissipation ratings for maximum permissible loss;
in general maximum dissipation rating is 70 to 80 percent.
Over current Protection and Thermal shut down function
Over current protection and Thermal shut down function are designed in these products, but these are not designed to
constantly ensure the suppression of the device within operation limits. Depending on the condition during actual usage, it
could affect the electrical characteristic specification and reliability. Also note that if output pins and GND pins are not
completely shorted out, these products might break down.
When using these products, please read through and understand the concept of dissipation for absolute maximum ratings
from the above mention or our ‘Semiconductor Reliability Handbook’. Then use these products under absolute maximum
ratings in any condition. Furthermore, Toshiba recommends inserting failsafe system into the design.
