TAR5S15U ~ TAR5S50U
Point Regulators (Low-Dropout Regulators)
The TAR5SxxU Series consists of general-purpose bipolar LDO
regulators with an on/off control pin and features
overtemperature and overcurrent protection circuits.
Features
• Low standby current
• Overtemperature and overcurrent protections
• Wide operating voltage range
• High maximum output current
• Low input-to-output voltage differential
• Small package (UFV package similar to SOT-353)
• Allows use of ceramic capacitors as the input and output
capacitors.
Pin Assignment (Top View)
The overtemperature and overcurrent protection features are not intended to guarantee correct operation below
the absolute maximum ratings.
Do not use the TAR5SxxU under conditions where the absolute maximum ratings may be exceeded.

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).

Application Notes
1. Recommended Application Circuit
The above figure shows the recommended application circuit for the TAR5SxxU. Capacitors should be
connected to VIN and VOUT for input/output stabilization.
If on/off control is not required, it is recommended to connect the CONTROL pin (pin 1) to VCC.
2. Power Dissipation
The power dissipation rating (450 mW) is measured on a board shown below. More power can be safely
dissipated by reducing the input voltage, output current and/or ambient temperature. It is recommended to
use the TAR5SxxU at 70% to 80% of the absolute maximum power dissipation.

3. Ripple Rejection
The TAR5SxxU feature a good power supply ripple rejection and input transient response, making them an
ideal solution for the RF block of cell phones.
4. NOISE Pin
The TAR5SxxU have a pin named NOISE. To reduce the output noise and ensure stable operation, a
capacitor should be inserted between the NOISE pin and GND. The capacitance value should be at least
0.0047 μF.
The output voltage rise time varies with the value of the capacitor connected to the NOISE pin.

5. Examples of Performance Curves When Ceramic Capacitors Are Used
The stable operating area (SOA) is an area where the output voltage does not go into oscillation. The
following figures represent the SOA obtained using an evaluation circuit shown below. The SOA is determined
by the equivalent series resistance (ESR) of the output capacitor and the output current. The TAR5SxxU
provide stable operation even when a ceramic capacitor is used as the output capacitor.
If the ripple frequency is 30 kHz or greater, the ripple rejection characteristics differ, depending on the type
of the output capacitor (ceramic or tantalum) as shown by the bottom figure on this page.
It is recommended to verify that TAR5SxxU operate properly under the intended conditions of use.
