The AP1117C is available in two types, fixed output voltage type or adjustable output voltage type. The fixed output voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options 1.5V, 2.85V, 3.0V and 3.6V are available by special order only. The output voltage range of the adjustable type is from 1.25V to 5V. The AP1117C consists of a 1.25V bandgap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection. The AP1117C devices are available in SOT-223 and TO-252 packages. TYPICAL APPLICATION CIRCUITS Note * 500K R1+R2 1000K, R1+R2 ~800K is recommended. All reserved by AnSC © 2007 Page: 1/...
