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)
