TCR5AM10A to TCR5AM18A
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR5AM10A to TCR5AM18A
500 mA CMOS Ultra Low Drop-Out Voltage Regulator
The TCR5AM10A to TCR5AM18A are CMOS single-output voltage
regulators with an on/off control input, featuring Ultra low dropout
voltage, 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 drop-out of 90 mV (Typ.) at
IOUT = 300 mA ( 1.1 V output, VBAT = 3.3 V ).
These voltage regulators are available in fixed output voltages
between 1.0 V and 1.8 V, and capable of driving up to 500 mA. Other
features include over-current protection, over-temperature protection,
Under-voltage-lockout and Auto-discharge function.
The TCR5AM10A to TCR5AM18A 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
TCR5AM10A to TCR5AM18A, these devices are ideal for portable
applications that require high-density board assembly such as
cellular phones.

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
●
Output Capacitors
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. And Toshiba recommend
the ESR of ceramic capacitor is under 10 Ω. For stable operation, please use over 1.0 μF Input capacitor, 1.0 μF Bias
capacitor and 2.2 μF output ceramic capacitor.
●
Mounting
The long distance between IC and output capacitor might affect phase assurance by impedance in wire and inductor.
For stable power supply, output capacitor need to mount near IC as much as possible. Also VIN and GND pattern
need to be 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
surrounding 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 be 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 recommend inserting failsafe system into the design.
