Features & Applications
The ST1L05CPU33R is a low drop linear voltage regulator capable of supplying up to 1.3 A output current. The output voltage is fixed at 1.8 V, 2.5 V, 3.3 V and Adjustable. It is available in three different versions with different pin outs.

The ST1L05 is stable with low ESR output ceramic capacitors. Internal protection circuitry includes thermal protection with hysteresis and overcurrent limiting. The ST1L05 is especially suitable for data storage applications such as HDDs, where it can be used to supply the 3.3 V required by read channel and memory chips.

Features:

  • Fixed output voltage: 1.8 V, 2.5 V, 3.3 V and ADJ
  • Output voltage tolerance: ±2% at 25 °C
  • Output current capability: 1.3 A
  • Very low quiescent current: max 650 μA Over temperature range
  • Typ. dropout 0.3 V (@ IO =1.3 A)
  • Enable function for the B, C and D versions
  • Power Good function for the B and D versions
  • Stable with low ESR ceramic capacitors
  • Thermal shutdown protection with hysteresis
  • Overcurrent protection
  • Operating junction temperature range: from 0 to 125 °C
