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.

ELECTRICAL SPECIFICATIONS

Specifications with standard type are for an Operating Junction Temperature of TJ = 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, VIN = 4.5V to 30V, CIN = 1uF, TJ = –40°C to 125°C.
