Applications
The GS2231 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 3A. It operates with a VIN
as low as 1.6V and VPP voltage 5V with output
voltage programmable as low as 0.8V.
The GS2231 features ultra low dropout, ideal for
applications where VOUT is very close to VIN.
Additionally, the GS2231 has an enable pin to
further reduce power dissipation while shutdown.
The GS2231 provides excellent regulation over
variations in line, load and temperature. The
GS2231 provides a power OK signal to indicate if
the voltage level of VO reaches 92% of its rating
value.
The GS2231 is available in the power PSOP-8
package. It is available with adjustable using
external resistors.
