General Description
The G9662 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 2 amps. It operates with a V_IN as low as 1.8V and
VPP voltage 5V with output voltage programmable as
low as 1.5V. The G9662 features ultra low dropout,
ideal for applications where V_OUT is very close to V_IN.
Additionally, the G9662 has an enable pin to further
reduce power dissipation while shutdown. The G9662
provides excellent regulation over variations in line,
load and temperature. The G9662 provides a power
OK signal to indicate if the voltage level of VO reaches
92% of its rating value.
The G9662 is available in the power TDFN3X3-10
package.
