    8178 PRODUCT PREVIEW (Subject to change without notice) April 5, 1996 Data Sheet 27468.22 LOW-DROPOUT, 7.7 V PREREGULATOR Designed specifically to meet the stringent requirements of automotive applications, the A8178LLR and A8178LLT provide an output voltage of 7.7 V ±15% for supply voltages greater than 6.9 V. They also provide a low-dropout tracking output for supply voltages down to 2.5 V. These regulators are intended to be used with sensitive automotive electronics systems that do not have the capability of low dropout operation and cannot withstand the high-voltage transients typical of automotive applications. These 7.
