Preliminary Data Sheet - E l e c t r i c a l C h a r a c t e r i s t i c s
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.
6.1.2 LIN Transceiver
(4.5V < VCC < 5.5V; 6V < VSUP < 18V; -40ºC < TJ < 150ºC, VBUS is the voltage on the LIN node. All voltages are with respect to ground (VSS);
positive current flows into the pin.
