Description

The LP38856 is a high-current, fast-response regulator which can maintain output voltage regulation with an extremely low input-to-output voltage drop. Fabricated on a CMOS process, the device operates from two input voltages: VBIAS provides power for the internal bias and control circuits, as well as drive for the gate of the N-MOS power transistor, while VIN supplies power to the load.

Key Features

  • 1 Input Voltage: 1.1 V to 5.5 V
  • Wide VBIAS Supply Operating Range: 3 V to 5.5 V
  • Standard VOUT: 0.8 V and 1.2 V
  • Stable with 10-µF Ceramic Capacitors
  • Dropout Voltage of 240 mV (Typical) at 3-A Load Current
  • Precision Output Voltage Across All Line and Load Conditions: – ±1% for TJ = 25°C – ±2% for 0°C ≤ TJ ≤ +125°C – ±3% for –40°C ≤ TJ ≤ +125°C
  • Overtemperature and Overcurrent Protection
  • 40°C to +125°C Operating Temperature Range
