AP1158ADS
Active Noise Filter IC
1. General Description
AP1158ADS is active noise filter IC, which can extremely reduce the ripple noise on the power supply line.
The ripple filter can be composed of few external components with low input-output voltage drop (Vdrop).
Vdrop can be set by external resistance. It is packaged in SOT23-5 and suitable for small set.
2. Feature
 Low Vdrop ripple filter can be composed of few parts.
 Built-in PNP power transistor
 Output Current 150mA
 Ripple Rejection 66dB at 1kHz
 Input Voltage Range 1.8V～14.0V
 Quiescent Current 65μA at Iout=0mA
 Internal on/off function (High active)
 Built-in Short-circuit Protection and Thermal Shutdown Protection
 Built-in Bias Over-current Blocking Circuit
 Available to use as low Vdrop / low noise regulator.
 Small Package SOT23-5
3. Applications
 Audio Equipment (Car stereo)
 Image equipment (car navigation system)
