TLS850A4TEV50 The TLS850A4TEV50 is a high performance, low dropout linear voltage regulator and ultra-low quiescent current for 5.0 V supply in a PG-TO252-3 package
The input voltage range of 3.7 V to 40 V and ultra-low quiescent current of 4.3 μA at light load make the device perfectly suitable for automotive supply systems or other supply systems that are permanently connected to the battery. The loop concept combines fast regulation and very high stability while requiring only one small ceramic capacitor of 4.7 μF at the output. Below an output current of 100 mA the typical dropout voltage is below 190mV. The operating range starts at an input voltage of only 3.7 V (extended operating range). This makes the TLS850A4TEV50 suitable for automotive systems that need to operate during cranking condition.
Internal protection features, such as output current limitation and overtemperature shutdown, are designed to protect the device from immediate damage caused by failures such as output shorted to GND, overcurrent condition and overtemperature condition.
This product is also available in 300mA: TLS830A4EPV50
