1 / 15 page © Semiconductor Components Industries, LLC, 2010 May, 2010 − Rev. 3 1 Publication Order Number: NCP508/D NCP508 Very Low Noise, Fast Turn On, 50 mA Low Dropout Voltage Regulator The NCP508 is a 50 mA low noise voltage regulator, designed to exhibit fast turn on time and high ripple rejection. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits. The NCP508 has been designed for use with ceramic capacitors. The device is housed in SC−88A and WDFN6 1.5x1.5 packages. Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0, and 3.3. Other voltages are available in 100 mV steps. Features • Very Low Noise at 39 mVrms without a Bypass Capacitor • High Ripple Rejection of 70 dB at 1 kHz • Low Dropout Voltage of 140 mV (typ) at 30 mA • Tight Load Regulation, typically 6 mV for DIout = 50 mA • Fast Enable Turn−On time of 20 msec • Logic Level Enable • ESR can vary from a few mW to 3 W • These are Pb−Free Devices Typical Applications • RF Subsystems in Handsets • Noise Sensitive Circuits; VCOs, PLL Vout Battery or Unregulated Voltage C1 1m C2 1m OFF ON 1 2 3 5 4 Figure 1.
