The AHK1117 is a Positive Linear Regulator
designed to deliver 1 amp. It features adjustable
or fixed output voltages and excellent
performance over line and load variations. The
device is able to protect itself and the load from
short circuit conditions with integrated current
limiting circuitry. Thermal shutdown is activated
to prevent damage under extreme conditions.
The AHK1117 is available in surface mount SOT-
223 or TO-252 (DPAK), and through-hole TO-220
packages.
