TLS850F1TA V50

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.
