EC8330 – 3A Low Dropout Regulator with Enable

General description

The EC8330 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 3 amps. It operates with a VIN  as low as 1.6V and VPP voltage 5V with output voltage programmable as low as 0.8V. The EC8330 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally,the EC8330 has an enable pin to further reduce power dissipation while shutdown. The EC8330 provides excellent  regulation over variations in line,load and temperature. The EC8330 provides a power OKsignal to indicate if the voltage level of VO reaches 92% of its rating value. The EC8330 is available in the power SOP-8(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.
