Description
The TLS850B0TEV33 is a high performance, very low dropout linear voltage regulator for 3.3 V supply in a PGTO252-5 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

Overview
operating range). This makes the TLS850B0TEV33 suitable for automotive systems that need to operate
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. TLS850B0TEV33 is designed to
operate stable with low ESR ceramic capacitors.

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 TLS850B0TEV33
limits the output current and the output voltage decreases.
The overtemperature shutdown circuit prevents the TLS850B0TEV33 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 TLS850B0TEV33.

Enable
The TLS850B0TEV33 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.
