General Description
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.
Features
Guaranteed 1.2V max Dropout at max current
Adjustable or Factory programmed output
voltages
Excellent performance over line, load
Current limit protection
Over-Temperature protection
SOT-223, TO-252 (DPAK) and TO-220
packages
Applications
Active SCSI Terminators
High Efficiency Linear Regulators
Post Regulators for Switching Supplies
Battery Chargers
5V to 3.3V Linear Regulators
