Description
The GM6251's combine high accuracy with very low power
consumption, providing high output current even when the
application requires extremely low input-output voltage dif-
ferential.
The GM6251's include a precision voltage reference, an er-
ror correction circuit, over-temperature protection, and a
current limited output driver. Fast transient response to
load variations provides excellent stability under dynamic
load conditions.
The GM6251's come in SOT-25 (150mW), SOT-89
(500mW) and TO-92 packages.
