800mA Low Dropout Voltage Regulator
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
Power Dissipation ................................ Internally Limited
Lead Temperature (Soldering, 5 sec) ..................... 260°C
Storage Temperature .............................. -65°C to 150°C
Operating Junction Temperature Range ... -40°C to +125°C
Input Supply Voltage .............................................. 20V
Input to Output Voltage ........................................18.8V
ESD Rating (HBM - Human Body Model) .................... 2kV
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Ambient Temperature of TA = 25°C only; limits applying over the full
Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for
reference purposes only. Unless otherwise indicated, CIN = COUT =10µF, TA= 25°C.
