FAN1951 - 1.5A Low-Voltage Low-Dropout Regulator

General Description

The FAN1950 and FAN1951 are 1.5A low-dropout linear regulators that provide a low voltage, high current output with a minimum of external components.

Both of these devices use a PNP output pass element achieving a maximum 500mV dropout at 1.5A load current.

Key Features

  • 1.5A minimum guaranteed output current.
  • 500mV maximum dropout at 1.5A Ideal for 2.5V to 1.8V or 1.65V conversion Ideal for 3.0V to 2.5V conversion.
  • Current Limiting and Thermal shutdown.
  • External Shut-down control (FAN1951 only).
  • Error flag output (FAN1951 only).
  • Fast transient response.
  • Low ground current General.
