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

• Pb−Free Packages are Available
