NCP4687

NCP4687 500 mA, High PSRR, LDO Linear Voltage Regulator The NCP4687 is a CMOS 500 mA LDO linear voltage regulator with high output voltage accuracy which features a high ripple rejection, low supply current with low dropout and chip enable with built−in low RDS(on) NMOS transistor for fast output capacitor discharging as option. The device is composed of the voltage reference unit, error amplifier, resistor divider for output voltage sensing or precise output voltage setting. The current limit and thermal shutdown makes the device very suitable for industrial applications and portable communication equipments. Features Operating Input Voltage Range: 2.5 V to 5.25 V Output Voltage Range: 0.7 to 3.6 V (available in 0.1 V steps) ±0.8% Output Voltage Accuracy @ Vout > 1.8 V Output noise : 40 mVrms Line Regulation: 0.02%/V Current Limit Circuit High PSRR: 75 dB at 1 kHz, 70 dB at 10 kHz Thermal Shutdown Available in SOT−23−5, SOT−89−5 and uDFN 1.2 x 1.2 mm Packages These Devices are Pb−Free and are RoHS Compliant Typical Applications Home Appliances, Industrial Equipment DVB−T and DVB−S Receivers Car Audio Equipment, Navigation Systems Notebook Adaptors, LCD TVs, Cordless Phones and Private LAN Systems NCP4687x VIN VIN VOUT VOUT C1 1.0 mF CE SENSE GND C2 1.0 mF http://onsemi.com MARKING DIAGRAMS SOT89−5 CASE 528AB 1 XXX XZZ XDFN6 CASE 711AH XX MM 1 SOT−23−5 CASE 1212 XXXMM 1 XX, XXX= Specific Device Code ZZ = Lot Code MM = Date Code ORD...
