Description
LDO1 is a low drop out voltage regulation module that can be used to provide 9-step program-
mable output voltages and 150 mA of maximum load current. It is designed to be integrated with
other analog cells, digital logic, microcontrollers, DSP cores, and memory blocks into system-on-
chip products. An internal reference voltage (bandgap voltage) is provided to the regulator, so
only a compensation capacitor connected at the output node versus ground is needed for cor-
rect operations.
