TLS850B0TBV33ATMA1

固定LDO稳压器, AEC-Q100, 3V至40V, 300mV压降, 3.3V/500mA输出, TO-263-5

Description:

The TLS850B0TBV33 is a high performance, very low dropout linear voltage regulator for 3.3 V supply in a PGTO263-

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 while requiring only one small ceramic

capacitor of 1 μF at the output. Below an output current of 100 mA the typical dropout voltage of 100mV is

very low. The operating range starts at an input voltage of only 3 V extended operating range. This makes the

TLS850B0TBV33 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 like output current limitation and overtemperature shutdown protect the device

from immediate damage due to failures such as output shorted to GND, overcurrent and overtemperature.
