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 maxi-
mum 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 condi-
tions. 1.8V and 2.5V fixed output versions are available.
3.3V, 1.65V and 1.5V options are available upon request.
