Functional Description

The TLS820D0 is a high performance very low dropout linear voltage regulator for 5 V (TLS820D0V50) or 3.3 V

(TLS820D0V33) 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 TLS820D0

provides an output voltage accuracy of 2 % and a maximum output current up to 200 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 (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 TLS820D0 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.

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.
