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.
