Features, Applications


1.5A minimum guaranteed output current 500mV maximum dropout at 1.5A Ideal for or 1.65V conversion Ideal for 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

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. In addition these devices offer overcurrent limit and thermal shutdown features to ensure full protection. The FAN1951 offers a logic level enable pin and an error flag output to indicate undervoltage and over-current conditions. 1.8V and 2.5V fixed output versions are available. 3.3V, 1.65V and 1.5V options are available upon request.
