Automotive Low Dropout (LDO), Ultra Low Quiescent Current Linear Voltage
Regulator OPTIREG™ TLS830A4EPV50

THERMALMODEL=10

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 40V 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 conditions.
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
