General Description

The LP38852-ADJ is a high-current, fast-response regulator which can maintain output voltage regulation with extremely low input-to-output voltage drop.

Fabricated on a CMOS process, the device operates from two input voltages: VBIAS provides voltage to drive the gate of the N-MOS power transistor, while VIN is the input voltage which supplies power to the load.

The use of an external bias rail allows the part to operate from ultralow VIN voltages.

Key Features

  • 1 Input VIN Range 0.93 V to 5.5 V.
  • Adjustable VOUT Range 0.8 V to 1.8 V.
  • Wide VBIAS Supply Operating Range 3 V to 5.5 V.
  • Dropout Voltage of 130 mV (Typical) at 1.5-A Load Current.
  • Precision Output Voltage Across All Line and Load Conditions:.
  • ±1.5% VADJ for TJ = 25°C.
  • ±2% VADJ for 0°C ≤ TJ ≤ +125°C.
  • ±3% VADJ for.
  • 40°C ≤ TJ ≤ +125°C.
  • Overtemperature and Overcurrent Protection.
  • Stable with 10-µF Ceram.
