LP38691-Q1 - 500-mA Low-Dropout CMOS Linear Regulators

Download the LP38691-Q1 datasheet PDF. This datasheet also covers the LP38691 variant, as both devices belong to the same 500-ma low-dropout cmos linear regulators family and are provided as variant models within a single manufacturer datasheet.

General Description

The LP3869x low-dropout CMOS linear regulators provide tight output tolerance (2% typical), extremely low dropout voltage (250 mV at 500-mA load current, VOUT = 5 V), and excellent AC performance using ultralow equivalent series resistance (ESR) ceramic output capacitors.

Key Features

  • 1 Wide Input Voltage Range (2.7 V to 10 V).
  • All WSON Options are Available as AEC-Q100 Grade 1.
  • 2% Output Accuracy (25°C).
  • Low Dropout Voltage: 250 mV at 500 mA (Typical, 5 V Out).
  • Precision (Trimmed) Bandgap Reference.
  • Ensured Specifications for.
  • 40°C to 125°C.
  • 1-µA Off-State Quiescent Current.
  • Thermal Overload Protection.
  • Foldback Current Limiting.
  • Ground Pin Current: 55 µA (typical) at full load.
