DESCRIPTION

· AP1158 is an active filter IC for low-frequency noise in audio systems.

· It replaces discrete noise filters (RC/LC) with a compact design and low drop-out voltage.

· Can function as a low I/O voltage/low noise regulator (external reference voltage required).

· Includes built-in thermal shutdown protection.

· Available in SOT23-5 (AP1158ADSXX) and PLP1822-6 (AP1158AEUXX) packages.

FEATURES

· Operating temperature: -40°C to 85°C.

· Operating voltage: 1.8V to 14V.

· Output current: 150mA.

· Ripple rejection: 66dB at 1kHz.

· Suitable for very low noise applications.

· Compatible with small ceramic capacitors.

· Built-in thermal shutdown.

APPLICATIONS

· RF power supplies.

· PLL, VCO, Mixer, LNA circuits.

· Low noise image sensor units.

· Digital still cameras.

· High-speed/high-precision A-D, D-A converters, amplifiers.

· Audio equipment.
