AHK1117
1 Amp Linear Regulator
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 SOT­223 or TO-252 (DPAK), and through-hole TO-220 packages.
