The TLS810A1LD V33 is a linear voltage regulator featuring wide input voltage range, low drop out voltage and ultra low quiescent current.With an input voltage range of 2.75 V to 42 V and ultra low quiescent of only 5 μA, the regulator is perfectly suitable for automotive or any other supply systems connected permanently to the battery. The TLS810A1LDV33 is the fixed 3.3 V output version with an accuracy of 2% and output current capability up to 100 mA. The new regulation concept implemented in TLS810A1 combines fast regulation and very good stability while requiring only a small ceramic capacitor of 1 μF at the output. The tracking region starts already at input voltages of 2.75 V (extended operating range). This makes the TLS810A1 also suitable to supply automotive systems that need to operate during cranking condition.Summary of Features•Ultra Low Quiescent Current of 5 μA•Wide Input Voltage Range of 2.75 V to 42 V•Output Current Capacity up to 100 mA•Low Drop Out Voltage of typ. 250mV @ 100 mA•Output Current Limit Protection•Overtemperature Shutdown•Available in PG-TSON-10 Package•Wide Temperature Range•Green Product (RoHS Compliant)•AEC QualifiedBenefits•Functional input voltage range starts at 2.75 V and very low dropout voltage: suitable for cranking•Ultra-low quiescent current and current consumption: power saving for battery•Stable with 1 μF output capacitor: PCB space and cost savings•Excellent transient robustness: smaller input capacitors hence lower input filtering costsPotential Applications•Applications with direct battery connection•Automotive general ECUs•Infotainment, alarm, dashboard•RKE, immobilizer, gateway
