... AME, Inc. AME1085 n General Description The AME1085 low-dropout positive voltage regu- lator available in fixed and adjustable output voltage versions. Overcurrent and thermal protection are integrated onto the chip. Output current will limit as it reaches the pre-set current or temperature limit. At full rated output current the dropout voltage is 1 ...

... AME, Inc. AME1085 5. Thermal Consideration The AME1085 series contain thermal limiting circuitry designed to protect itself for over-temperature conditions. Even for normal load conditions, maximum junction tem- perature ratings must not be exceeded. As mention in thermal protection section, we need to consider all sources of thermal resistance between junction and am- bient ...
