Product Overview NCP508: Linear Voltage Regulator, LDO, Low Noise, Fast Turn On, 50 mA For complete documentation, see the data sheet Product Description The NCP508 is a 50 mA low noise, low dropout (LDO) linear voltage regulator, designed to exhibit fast turn-on time, low noise and high ripple rejection. The device is robust, incorporating current limiting and temperature protection circuitry. The NCP508 has been designed for use with low cost ceramic capacitors and is housed in an SC-88A or a tiny 1.5x1.5 mm WDFN package. Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0, and 3.3. Other voltages may be available, along with Automotive qualified versions of the device: contact your local sales representative. Features • • • • Very Low Noise at 39 uVrms without a Bypass Capacitor Fast enable response (20 usec) High Ripple Rejection of 70 dB at 1 kHz Can use decoupling capacitors with ESR ranging from milliohms to 3 ohms. Applications • RF Subsystems in Handsets • Noise sensitive circuits; VCOs, PLL Benefits • • • • Suitable for audio or measurement applications Responds quickly to a turn-on signal Provides a clean voltage rail from a battery or noisey supply Suitable for cheap ceramic capacitors End Products • Bluetooth headsets • Meters, Instrumentation Part Electrical Specifications Product Compliance Status Output Polarity VO (V) IO Typ (A) VI Max (V) VDO Typ (V) Iq Typ (mA) PSRR (dB) Noise (µVrms) Package Type NCP508MT15TBG Pb-free Active Single Positive 1.5 0.05 13 0.155 0.3 70 39 WDFN-6 Active Single Positive 1.8 0.05 13 0.155 0.3 70 39 WDFN-6 Active Single Positive 2.5 0.05 13 0.155 0.3 70 39 WDFN-6 Active Single Positive 2.8 0.05 13 0.155 0.3 70 39 WDFN-6 Active Single Positive 3 0.05 13 0.155 0.3 70 39 WDFN-6 Active Single Positive 3.3 0.05 13 0.155 0.3 70 39 WDFN-6 Active Single Positive 1.5 0.05 13 0.155 0.3 70 39 SC-88A5 / SC70-5 / SOT323-5 Active Single Positive 1.8 0.05 13 0.155 0.3 70 39 SC-88A5 / SC70-5 / SOT323-5 Active Single Positive 2.5 0.05 13 0.155 0.3 70 39 SC-88A5 / SC70-5 / SOT323-5 Active Single Positive 2.8 0.05 13 0.155 0.3 70 39 SC-88A5 / SC70-5 / SOT323-5 Active Single Positive 3 0.05 13 0.155 0.3 70 39 SC-88A5 / SC70-5 / SOT323-5 Active Single Positive 3.3 0.05 13 0.155 0.3 70 39 SC-88A5 / SC70-5 / SOT323-5 Halide free NCP508MT18TBG Pb-free Halide free NCP508MT25TBG Pb-free Halide free NCP508MT28TBG Pb-free Halide free NCP508MT30TBG Pb-free Halide free NCP508MT33TBG Pb-free Halide free NCP508SQ15T1G Pb-free Halide free NCP508SQ18T1G Pb-free Halide free NCP508SQ25T1G Pb-free Halide free NCP508SQ28T1G Pb-free Halide free NCP508SQ30T1G Pb-free Halide free NCP508SQ33T1G Pb-free Halide free For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016
