Introduction

AI Translation

LP3869x low dropout CMOS linear regulators feature tight output tolerance (2% typical) and ultra-low dropout (250mV at 500mA load current, V<sub>OUT</sub> = 5V), and deliver excellent AC performance with ultra-low ESR ceramic output capacitors. The regulators are available in low thermal resistance WSON, SOT-223, and TO-252 packages, enabling full-current operation even at elevated ambient temperatures. The use of a PMOS power transistor eliminates the need for DC base drive current biasing, keeping ground pin current below 100μA regardless of load current, input voltage, or operating temperature.

  • Dropout voltage: 250mV (typical) at 500mA (5V output voltage typical)
  • Ground pin current: 55μA (typical) at full load
  • Precision output voltage: 2% accuracy (at 25°C)
