General Description
The G964 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 1 amps. It operates with a VIN as low as 1.4V and VPP voltage 5V with output voltage programmable as low as 0.8V. The G964 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the G964 has an enable pin to further reduce power dissipation while shutdown. The G964 provides excellent regulation over variations in line, load and temperature. The G964 provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value.
The G964 is available in the power SOP-8 package. It is available with 1.2V, 1.5V, 1.8V and 2.5V internally preset outputs that are also adjustable using external resistors.
