TLS830A4EPV50 | Ultra low quiescent current linear voltage regulator

Overview

The OPTIREG™ linear voltage regulator TLS830A4EPV50 is a linear voltage regulator with high performance, low dropout voltage and ultra low quiescent current. With only 4.3 μA typical quiescent current at light load and an input voltage range of 3.2 V to 40 V the device is 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. The operating range starts at an input voltage of 3.2 V (extended operating range). This makes the device suitable for automotive systems that need to operate in 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
overtemperature condition

This product is also available in 500mA: TLS850A4TEV50
