Description
The TLS850B0TEV50 is a high performance, very low dropout linear voltage regulator for 5 V supply in a PG-
TO252-5 package.
The input voltage range of 3 V to 40 V and a very low quiescent current of 20 µA make it the perfect match for
automotive or other supply systems connected to the battery permanently.
The new loop concept combines fast regulation and very high stability. Below an output current of 100 mA the
typical dropout voltage is below 100 mV. The operating range starts at an input voltage of only 3 V (extended

during cranking condition.
The device can be switched on and off by the Enable feature.
Internal protection features such as output current limitation and overtemperature shutdown protect the
device from immediate damage due to failures such as output shorted to GND, overcurrent and
overtemperature.
Choosing external components
An input capacitor CI is recommended to compensate line influences.
The output capacitor CQ is necessary for the stability of the regulating circuit. TLS850B0TEV50 is designed to
operate stable with low ESR ceramic capacitors.

Block description and electrical characteristics

Block description and electrical characteristics
5.1
Voltage regulation
The output voltage VQ is divided by a resistor network. This fractional voltage is compared to an internal
voltage reference and the pass transistor is driven accordingly.
The control loop stability depends on the following factors:
•
•
•
•
output capacitor CQ
load current
chip temperature
internal circuit design
To ensure stable operation, the output capacitor’s capacitance and its equivalent series resistor (ESR)
requirements given in “Functional range” on Page 7 must be maintained. Because the output capacitor
must buffer load steps, it must be sized according to the requirements of the application.
An input capacitor CI is recommended to compensate line influences. In order to block influences such as
pulses and HF distortion at the input, an additional reverse polarity protection diode and a combination of
several capacitors for filtering should be used. Connect the capacitors close to the component’s terminals.
In order to prevent overshoots during start-up, a slope control function is implemented. This significantly
reduces output voltage overshoots during start-up, mostly independent from load.
If the load current exceeds the specified limit, for example due to a short circuit, then the TLS850B0TEV50
limits the output current and the output voltage decreases.
The overtemperature shutdown circuit prevents the TLS850B0TEV50 from immediate destruction in fault
condition, for example due to a permanent short-circuit at the output, by switching off the power stage. After
the chip has cooled down, the regulator restarts. This leads to an oscillatory behavior of the output voltage
until the fault is removed. However, any junction temperature above 150°C is outside the maximum ratings
and therefore significantly reduces the life time of the TLS850B0TEV50.

Block description and electrical characteristics

Enable
The TLS850B0TEV50 can be switched on and off by the enable feature. Applying a “high” level as specified
below (for example battery voltage) to the EN pin enables the device. Applying a “low” level as specified below
(for example GND) shuts down the device. If a signal with slow slope is applied to the EN pin, then the built in
hysteresis of the enable feature avoids toggling between ON/OFF state.

Application diagram
Note:
This is a very simplified example of an application circuit. The function must be verified in the real
application.
6.2
Selection of external components
6.2.1
Input pin
Figure 5 shows the typical input circuitry for a linear voltage regulator. A ceramic capacitor at the input, in the
range of 100 nF to 470 nF, is recommended to filter the high frequency disturbances imposed by the line, for
example ISO pulses 3a/b. This capacitor must be placed very close to the input pin of the linear voltage
regulator on the PCB.
An aluminum electrolytic capacitor in the range of 10 µF to 470 µF is recommended as an input buffer to damp
high energy pulses, such as ISO pulse 2a. This capacitor must be placed close to the input pin of the linear
voltage regulator.
An overvoltage suppressor diode can be used to further suppress any high voltage beyond the maximum
rating of the linear voltage regulator and to protect the device from damage due to overvoltage.
The external components at the input pin are optional, but they are recommended in case of possible external
disturbances.
6.2.2
Output pin
An output capacitor is mandatory for the stability of linear voltage regulators.
The requirement to the output capacitor is given in “Functional range” on Page 7.

2017-09-26
TLS850B0TEV50
Low dropout linear voltage regulator
Application information
TLS850B0TEV50 is designed to be also stable with low ESR capacitors. According to the automotive
requirements, ceramic capacitors with X5R or X7R dielectrics are recommended.
The output capacitor should be placed as close as possible to the voltage regulator’s output pin and GND pin,
on the same side of the PCB as the regulator itself.
In case of input voltage transients or load current transients, the capacitance should be dimensioned in
accordance and verified in the real application that the output stability requirements are fulfilled.
6.3
Thermal considerations
the total power dissipation can be calculated from the known input voltage, the output voltage and the load
profile of the application:
PD = (VI - VQ) × IQ + VI × Iq
(6.1)
with
•
•
•
•
•
PD: continuous power dissipation
VI: input voltage
VQ: output voltage
IQ: output current
Iq: quiescent current
The maximum acceptable thermal resistance RthJA is:
RthJA,max = ( Tj,max - Ta ) / PD
(6.2)
with
•
•
T
j,max: maximum allowed junction temperature
Ta: ambient temperature
Based on the above calculation the proper PCB type and the necessary heat sink area can be determined with
reference to the specification in “Thermal resistance” on Page 8.
6.4
Reverse polarity protection
TLS850B0TEV50 is not protected against reverse polarity faults and must be protected by external
components against negative supply voltage. An external reverse polarity diode is necessary. The absolute
maximum ratings of the device as specified in “Absolute maximum ratings” on Page 6 must be maintained.
