Infineon TLS810A1LDV33XUMA1, 1 Linear Voltage, Voltage Regulator 100mA, 3.37 V 10-Pin, TSON

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.
