Description
The OPTIREG™ linear TLS820F0ELVxx is a high performance very low dropout linear voltage regulator for 5 V
(TLS820F0ELV50) or 3.3 V (TLS820F0ELV33) supply in a PG-SSOP-14 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 TLS820F0
provides an output voltage accuracy of 2 % and a maximum output current up to 200 mA.

OPTIREG™ linear TLS820F0ELVxx
Low dropout linear voltage regulator
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 (for 5 V device) and 80 mV (for 3.3 V device). The operating range starts already at input
voltages of only 3 V (extended operating range). This makes the TLS820F0 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 4.5.
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 4.7.
In addition, a watchdog circuit with flexible timings 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.
External components
An input capacitor C
I
is recommended to compensate line influences. The output capacitor C
Q
is necessary for
the stability of the regulating circuit. TLS820F0 is designed to be also stable with low ESR ceramic capacitors.
