FP9102-18XR-LF

FP9102 2A Low Dropout Regulator with Enable General Description The FP9102 is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage with very low dropout output voltage at up to 2A load. It can regulate the programmable output voltage to as low as 0.8V with a 5V VCC voltage and a minimum 1.6V VIN. The FP9102 features include ultra low dropout. It is ideal for applications where VOUT is very close to VIN. Additionally, there is an ENABLE pin to further reduce power dissipation while shutdown. The FP9102 provides excellent regulation over variations in line, load and temperature. The FP9102 provides a power GOOD signal to indicate if the voltage level of VOUT reaches 90% of its rating value. The FP9102 is available in the SOP-8L (Exposed Pad) package. It is available with 1.2V, 1.5V, 1.8V and 2.5V internally preset outputs that are also adjustable using external resistors.

Note 2: Regulation is measured at constant junction temperature by using a 2ms current pulse. Devices are tested for load regulation in the load range from 1mA to 2A Note 3: The dropout voltage is defined as VIN-VOUT, which is measured when VOUT is normal VOUT-100mV Note 4: Quiescent current is the difference between input and outputs. It is defined by IQ=IIN-IOUT under no load condition (IOUT=0mA). The total current drawn from the supply is the sum of the load current plus the ground pin current.
