A8178LLR - Low Dropout, 7.7 V Preregulator
Designed to meet the stringent requirements of automotive applications, the A8178LLR and A8178LLT provide an output voltage of 7.7 V ±15% of the supply voltage, greater than 6.9 V also provides a low dropout tracking output of the supply voltage to 2.5 V. The regulators are intended for use in Typical automotive applications where sensitive automotive electronic systems are not capable of low dropout operation and cannot withstand high voltage transients. These 7.7 V pre-regulators will withstand all ISO pulses (an external diode is required for ignition coil disconnect) and will have positive supply transients (noise) during carryover. These devices are available in small outline plastic transistor packages for surface mount applications. The A8178LLR is available in the smallest footprint SOT-23/TO-236AB; the A8178LLT is a SOT-89/TO-243AA trimmed for increased power dissipation in the package.
