80mA Low Noise Ultra Low Dropout Voltage Regulator
DESCRIPTION
The TS5204 series is an efficient linear voltage
regulator with ultra-low noise output, very low dropout
voltage (typically 20mV at light loads and 300mV at
80mA), and very low power consumption (500µA at
50mA), providing high output current even when the
application requires very low dropout voltage. The
TS5204 series is included a precision voltage reference,
error correction circuit, a current limited output driver,
over temperature shutdown and revered battery
protection.

Note:
4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
5. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 1mA to 80mA. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
6. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value
measured at 1V differential.
7. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
supply is the sum of the load current plus the ground pin current.
8. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a 80mA load pulse at V

=16V for t=10ms.

APPLICATION INFORMATION
TS5204 series is designed to provide 80mA of continuous current in a very small package. Maximum power
dissipation can be calculated based on the output current and the voltage drop across the part. To determine the
maximum power dissipation of the package, use the junction-ambient thermal resistance of the device and the
following basic equation:
P
D(MAX)
= [ T
J(MAX)
– T
A
] /R
ΘJA
Tj(max) is the maximum junction temperature of the die(125°C), and Ta is the ambient operating temperature.
R
ΘJA
is layout dependent, the actual power dissipation of the regulator circuit can be determined using the
equation:
P
D
= (V
IN
– V

) * I
OUT
+ V

Substituting P
D(MAX)
for P
D
and solving for the operating conditions that are critical to the application will give the
maximum operating conditions for the regulator circuit. For example, when operating the TS5204CX33 at room
temperature with a minimum footprint layout, the maximum input voltage for a set output current can be
determined as follows:
P
D(MAX)
= (125 C – 25 C) / 220 C/W
o
o

The junction to ambient thermal resistance for the minimum footprint is 220°C/W, the maximum power dissipation
must not be exceeded for proper operation. Using the output voltage of 3.3V and an output current of 80mA, the
maximum input voltage can be determined. From the electrical characteristics table, the maximum ground
current for 80mA output current is 2.5mA.

(max) = 6.85V
Therefore, a 3.3V application at 80mA of output current can accept a maximum input voltage of 6.85V in a SOT-
23 package.
Input Capacitor Requirement
An input capacitor of 0.1μF or greater is recommended when the device is more than 10” away from the bulk AC
supply capacitance or when the supply is a battery.

APPLICATION INFORMATION (CONTINUE)
Output Capacitor Requirement
The TS5204 series requires an output capacitor to maintain stability and improve transient response is necessary.
2.2μF minimum is recommended. Larger values improve the regulator’s transient response. The output capacitor
value may be increased without limit.
The output capacitor should have an ESR (effective series resistance) less than 5Ω and a resonant frequency
above 1MHz. Ultra-low ESR capacitors can cause a low amplitude oscillation on the output and/or under damped
transient response. Most of tantalum or aluminum electrolytic capacitors are adequate; film types will work. Since
many aluminum electrolytic have electrolytes that freeze at about –30°C, solid tantalums are recommended for
operation below –25°C. At lower values of output current, less output capacitance is required for output stability.
The capacitor can be reduced to 0.47μF for current below 10mA or 0.33μF for currents below 1mA
.
No Load Stability
The TS5204 series will remain stable and in regulation with no load, unlike many other voltage regulators. This is
especially important in CMOS RAM keep alive applications.
Dual Supply Operation
When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage
must be diode clamped to ground.
