6.1 Detailed System and Block Specifications
6.1.1 Low Dropout Regulator
The LDO is a linear voltage regulator, which provides a regulated (band-gap stabilized) output voltage (VCC) from the battery supply voltage
(VSUP).
(6V < VSUP < 18V; -40ºC < TJ < +150ºC; all voltages are with respect to ground (VSS); positive current flows into the pin), normal operating
mode if not otherwise mentioned.
