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
