LP3988H

Ultra-Low Noise and High PSRR LDO

Features

Description

⚫

Low current consumption: 24µA (Typ)

The LP3988H is a low-dropout voltage regulator with very

low noise and high PSRR in ultra-small package. The

LP3988H can deliver output current up to 600mA. The

output voltage could be selected to 1.8V, 2.5V, 2.8V, 3.0V

or 3.3V.

Wide input voltage range: 2.0V to 5.5V

High output voltage accuracy: ±1.5%

Ultra high PSRR: 98dB at 20mA/1kHz

Ultra low noise: 10 µV_RMS(TBD)

Low dropout voltage:

The LP3988H is integrated over current protection and

short circuit protection in order to protect system abnormal.

The input and output capacitor as small as 1µF will be

good enough for LP3988H.

−

165mV at 250mA (V_OUT= 1.8V)

480mV at 500mA (V_OUT= 1.8V)

The LP3988H is available in 4 pins ultra-small TDFN-4

package with only 1mm  1mm size or normal SOT23-5

package.
