EC8330 Datasheet, PDF (1/16 Pages) E-CMOS Corporation – 3A Low Dropout Regulator with Enable

3A Low Dropout Regulator with Enable
EC8330
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 OK
signal 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.
