Overview
Description
The TLS805B1 is a linear voltage regulator featuring wide input voltage range, low drop out voltage and ultra
low quiescent current.
With an input voltage range of 2.75 V to 42 V and ultra low quiescent of only 5.5 µA, the regulator is perfectly
suitable for automotive or any other supply systems connected permanently to the battery.
The TLS805B1LDV50 is the fixed 5 V output version with an accuracy of 2 % and output current capability up
to 50 mA.
The new regulation concept implemented in TLS805B1 combines fast regulation and very good stability while
requiring only a small ceramic capacitor of 1 μF at the output.
The tracking region starts already at input voltages of 2.75 V (extended operating range). This makes the
TLS805B1 also suitable to supply automotive systems that need to operate during cranking condition.
Internal protection features like output current limitation and overtemperature shutdown are implemented
to protect the device against immediate damage due to failures like output short circuit to GND, over-current
and over-temperature.
The device can be switched on and off by the Enable feature. When the device is switched off, the current
consumption is typically less than 1 µA.
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. Stability is guaranteed at values CQ≥ 1 µF and an ESR ≤ 100 Ω within the
whole operating range.

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 output capacitor CQ, the load current, the chip temperature and the
internal circuit structure. To ensure stable operation, the output capacitor’s capacitance and its equivalent
series resistor ESR requirements given in “Functional Range” on Page 8 have to be maintained. For details
see the typical performance graph Output Capacitor Series Resistor ESR(CQ) versus Output Current IQ.
Since the output capacitor is used to buffer load steps, it should be sized according to the application’s needs.
An input capacitor CI is not required for stability, but is recommended to compensate line fluctuations. An
additional reverse polarity protection diode and a combination of several capacitors for filtering should be
used, in case the input is connected directly to the battery line. Connect the capacitors close to the regulator
terminals.
In order to prevent overshoots during start-up, a smooth ramping up function is implemented. This ensures
almost no overshoots during start-up, mostly independent from load and output capacitance.
Whenever the load current exceeds the specified limit, e.g. in case of a short circuit, the output current is
limited and the output voltage decreases.
The overtemperature shutdown circuit prevents the IC from immediate destruction under fault conditions
(e.g. output continuously short-circuit) by switching off the power stage. After the chip has cooled down, the
regulator restarts. This oscillatory thermal behaviour causes the junction temperature to exceed the
maximum rating of 150°C and can significantly reduce the IC’s lifetime.

6.2.1
The typical input circuitry for a linear voltage regulator is shown in the application diagram above.
A ceramic capacitor at the input, in the range of 100 nF to 470 nF, is recommended to filter out the high
frequency disturbances imposed by the line e.g. 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
smooth out high energy pulses, such as ISO pulse 2a. This capacitor should be placed close to the input pin of
the linear voltage regulator on the PCB.
An overvoltage suppressor diode can be used to further suppress any high voltage beyond the maximum
rating of the linear voltage regulator and protect the device against any damage due to over-voltage.
The external components at the input are not mandatory for the operation of the voltage regulator, but they
are recommended in case of possible external disturbances.

Application Information
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 8. The graph “Output
Capacitor Series Resistor ESR(CQ) versus Output Current IQ” on Page 14 shows the stable operation range
of the device.
TLS805B1 is designed to be stable with extremely low ESR capacitors. According to the automotive
environment, ceramic capacitors with X5R or X7R dielectrics are recommended.
The output capacitor should be placed as close as possible to the regulator’s output and GND pins and on the
same side of the PCB as the regulator itself.
In case of rapid transients of input voltage or load current, the capacitance should be dimensioned in
accordance and verified in the real application that the output stability requirements are fulfilled.
6.3
Thermal Considerations
Knowing the input voltage, the output voltage and the load profile of the application, the total power
dissipation can be calculated:
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 can then be calculated:
Tj, max – Ta
RthJA, max = ---------------------------
PD
(6.2)
with
•
•
Tj,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 9.
Example
Application conditions:
VI = 13.5 V
VQ = 5 V
IQ = 40 mA
Ta = 105 °C
Data Sheet

Rev. 1.10 2016-04-20
TLS805B1LDV50
Application Information
Calculation of RthJA,max
:
PD = (VI – VQ) x IQ + VI x Iq
= (13.5V – 5V) x 40 mA + 13.5 V x 0.012 mA
= 0.34 W
R
thJA,max= (Tj,max – Ta) / PD
= (150 °C – 105 °C) / 0.34 W
= 132.35 K/W
As a result, the PCB design must ensure a thermal resistance RthJA lower than 132.35 K/W. According to
“Thermal Resistance” on Page 9, at least 300 mm2 heatsink area is needed on the FR4 1s0p PCB, or the FR4
2s2p board can be used.
6.4
Reverse Polarity Protection
TLS805B1 is not self protected against reverse polarity faults. To protect the device against negative supply
voltage, an external reverse polarity diode is needed, as shown in Figure 5. The absolute maximum ratings of
the device as specified in “Absolute Maximum Ratings” on Page 7 must be kept.
