Functional Description
Overview
The TLS850F1TAV50 is a high performance very low dropout linear voltage regulator for 5 V supply in a PG-
TO263-7 package.
With an input voltage range of 3 V to 40 V and very low quiescent of only 40 µA, these regulators are perfectly
suitable for automotive or any other supply systems connected to the battery permanently. The TLS850F1TAV50
provides an output voltage accuracy of 2 % and a maximum output current up to 500 mA.
The new loop concept combines fast regulation and very good stability while requiring only one small ceramic
capacitor of 1 µF at the output. At currents below 100 mA the device will have a very low typical dropout voltage
of only 70 mV. The operating range starts already at input voltages of only 3 V (extended operating range). This
makes the TLS850F1TAV50 also suitable to supply automotive systems that need to operate during cranking
condition.
The device can be switched on and off by the Enable feature as described in Chapter 5.5.
The output voltage is supervised by the Reset feature, including Undervoltage Reset, delayed Reset at Power-On
and an adjustable lower Reset Threshold, more details can be found in Chapter 5.7.
In addition, a Watchdog circuit with fixed timing is integrated to monitor the microcontroller‘s operation.
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-temperatures.
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. TLS850F1TAV50 is designed to be also stable with low ESR ceramic
capacitors.

Note:
1. Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2. Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not
designed for continuous repetitive operation.
