G969A Global Mixed-mode Technology 1.5A Low Dropout Regulator with Dual Input Voltage Features General Description The G969A 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 1.5 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 G969A features ultra low dropout, ideal for applications where VOUT is very close to VIN. The G969A provides excellent regulation over variations in line, load and temperature. The G969A provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value. Adjustable Output Low to 0.8V Input Voltage as Low as 1.4V and VPP Voltage 5V 300mV Dropout @ 1.5A, VO 1.2V Over Current and Over Temperature Protection Low Reverse Leakage (Output to Input ) Power MSOP-8 Packages ±2% Output Voltage 1.2V, 1.5V, 1.8V and 2.5V Options by Setting ADJ Pin Below 0.2V and Adjustable Externally Using Resistors VO Pull Low Resistance when Disable The G969A is available in the power MSOP-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.
