FP9101-1A Low Dropout Regulator with Enable


FP9101 1A Low Dropout Regulator with Enable
General Description
Download
 The FP9101 is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage and very low dropout voltage at up to 1A. It operates with a VIN as low as 1.6V and VDD voltage 5V with output voltage programmable as low as 0.8V. The FP9101 features include ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, there is an enable pin to further reduce power dissipation while shutdown. The FP9101 provides excellent regulation over variations in line, load and temperature. The FP9101 provides a power OK signal to indicate if the voltage level of VOUT reaches 90% of its rating value.
The FP9101 is available in the SOP8 package. It is available with 1.2V, 1.5V, 1.8V and 2.5V internally preset outputs that are also adjustable using external resistors
