General Description
TS5213 is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 50mV at
light loads and 320mV at 80mA), and very low ground current (225uA at 20mA), providing high output current even
when the application requires very low dropout voltage. The Chip Enable (EN) includes a CMOS or TTL compatible
input allows the output to be turned off to prolong battery life. When shutdown, power consumption drops nearly to
zero. TS5213 is included a precision voltage reference, error correction circuit, a current limited output driver, over
temperature shutdown and revered battery protection.

Electrical Specification (Continue)
Note 1: Exceeding the absolute maximum rating may damage the device.
Note 2: The maximum allowable power dissipation at any Ta is Pd(max) = [TJ(MAX) - Ta] + ӨJA. Exceeding the
maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into
thermal shutdown.
Note 3: Devices are ESD sensitive. Handling precautions recommended.
Note 4: The device is not guaranteed to function outside its operating rating.
Note 5: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total
temperature range.
Note 6: 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.
Note 7: 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.
Note 8: 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.
Note 9: 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 VIH =16V for
t=10mS.
Application Information
Enable Input
TS5213 series feature an active-high (>2V) enable (EN) input that allows ON/OFF control of the regulator. Current
drain reduces to “zero” when the device is shutdown, with only micro-amperes of leakage current. The EN is
compatible with CMOS logic interfacing. EN may be directly tied to VIH and pulled up to the maximum supply voltage.
Input Capacitor Requirement
An input capacitor of 0.17uF 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 TS5213 series requires an output capacitor to maintain stability and improve transient response is necessary.
The TS5213 is ultra stable, requiring only 0.47uF of output capacitance for stability. It is stable with all type of
capacitors, including the tiny, low-ESR ceramic chip capacitors. The output capacitor value may be increased without
limit.
No Load Stability
The TS5213 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.

Thermal Characteristics
TS5213 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:
PD(MAX) = [ TJ(MAX) – TA ] /ΘJA
TJ(MAX) is the maximum junction temperature of the die(125oC), and Ta is the ambient operating temperature. ΘJA is
layout dependent, the actual power dissipation of the regulator circuit can be determined using the equation:
PD = (VIN – VOUT) * IOUT + VIN * IGND
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 TS5213CX550 at room
temperature with a minimum footprint layout, the maximum input voltage for a set output current can be determined
as follows:
PD(MAX) = (125oC – 25oC) / 220oC/W
PD(MAX) = 455mW
The junction to ambient thermal resistance for the minimum footprint is 220oC/W, the maximum power dissipation
must not be exceeded for proper operation. Using the output voltage of 5.0V and an output current of 80mA, the
maximum input voltage can be determined. Form the electrical characteristics table, the maximum ground current for
80mA output current is 1mA.
445mW = (VIN – 5.0V ) * 80mA + VIN * 1.8mA
445mW = VIN * 80mA – 5.0 * 80mA + VIN * 1.8mA
445mW = VIN * 80mA – 400mW + VIN * 1.8mA
845mW = VIN * 81.8mA
VIN (max) = 10.33V
Therefore, a 5.0V application at 80mA of output current can accept a maximum input voltage of 10.33V in a SOT-25
package.
