Automotive Low Dropout (LDO) Linear Voltage Regulator OPTIREG™ TLS820F3ELV50
with watchdog and reset

THERMALMODEL=10

The OPTIREG™ linear TLS820F3ELV50 is a high-performance, low drop-out, fixed output voltage regulator
in a PG-SSOP-14 package. With an input voltage range of 3 V to 42 V and a very low quiescent current of only
26 µA, this regulator is perfectly suitable for automotive systems or other supply systems connected to the
battery permanently.

The TLS820F3ELV50 provides an output voltage accuracy of ±2% and a maximum output current of 200 mA.
The loop concept combines fast regulation and very good stability while requiring only one small ceramic capacitor
of 1 µF at the output. The operating range starts already at an input voltage of only 3 V (extended operating range).
This makes the TLS820F3ELV50 also suitable to supply automotive systems that need to operate during cranking conditions.
