LOW-DROPOUT,
7.7 V PREREGULATOR
Designed specifically to meet the stringent requirements of automo-
tive 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 automo-
tive electronics systems that do not have the capability of low dropout
operation and cannot withstand the high-voltage transients typical of
automotive applications. These 7.7 V preregulators will withstand all
ISO pulses (ignition coil disconnect requires an external diode) and will
continue to operate during positive power supply transients (noise).
These devices are supplied in small-outline plastic transistor
packages for surface-mount applications. The A8178LLR is supplied in
the minimum footprint SOT-23/TO-236AB; the A8178LLT is furnished in
the SOT-89/TO-243AA for increased allowable package power dissipa-
tion.
