General 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 500mV at 150mA at 5V version), and very low power consumption (600uA at

100mA), 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:

1. Exceeding the absolute maximum rating may damage the device.

2. The maximum allowable power dissipation at any Ta is Pd(max) = [T_J(MAX)- Ta] + Ө_JA. Exceeding the maximum

allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal

shutdown.

3. The device is not guaranteed to function outside its operating rating.

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 150mA (5V version) and 1mA to 120mA (V_OUT<5V version).

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 150mA load pulse at V_IN=16V for

t=10mS.

TS5204

150mA Low Noise LDO Voltage Regulator

Application Information

TS5204 series is designed to provide 150mA (5V version) 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] /Θ

Tj(max) is the maximum junction temperature of the die(125^oC), and Ta is the ambient operating temperature.

Θ_JAis layout dependent, the actual power dissipation of the regulator circuit can be determined using the

equation:

P_D= (V_IN– V_OUT) * I_OUT+ V_IN* I_GND

Substituting Pd(max) for Pd 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^oC – 25^oC) / 220^oC/W

The junction to ambient thermal resistance for the minimum footprint is 220^oC/W, the maximum power dissipation

must not be exceeded for proper operation. Using the output voltage of 3.3V and an output current of 120mA, the

maximum input voltage can be determined. From the electrical characteristics table, the maximum ground

current for 120mA output current is 2.5mA.

445mW = (V_IN– 3.3V ) * 120mA + V_IN* 2.5mA

445mW = V_IN* 120mA – 3.3 * 120mA + V_IN* 2.5mA

445mW = V_IN* 120mA – 395mW + V_IN* 2.5mA

840mW = V_IN* 122.5mA

V_IN(max) = 6.85V

Therefore, a 3.3V application at 120mA of output current can accept a maximum input voltage of 6.85V in a SOT-

23 package.

Input Capacitor Requirement

An input capacitor of 0.1uF 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.

Output Capacitor Requirement

The TS5204 series requires an output capacitor to maintain stability and improve transient response is necessary.

2.2uF 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^oC, solid tantalums are recommended for

operation below –25^oC. At lower values of output current, less output capacitance is required for output stability.

The capacitor can be reduced to 0.47uF for current below 10mA or 0.33uF 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.
