ST ST1L05 - ST1L05A ST1L05B - ST1L05C - ST1L05D handbook

About this manual

The ST1L05 family is a low drop linear voltage regulator capable of supplying up to 1.3 A output current. The output voltage is fixed at 1.8V, 2.5V, 3.3V, or Adjustable. It is available in three different versions with different pin outs.

Thanks to BiCMOS technology, the quiescent current is controlled and maintained below 650 µA over the entire allowed junction temperature range. The ST1L05 is stable with low ESR output ceramic capacitors. Internal protection circuitry includes thermal protection with hysteresis and overcurrent limiting.
