ESMT/EMP
EMP8733
Fast Ultra High-PSRR, Low-Noise 300mA CMOS
LDO in SOT-23 Package
General Description
The EMP8733 features ultra-high power supply rejection
ratio, low output voltage noise, low dropout voltage,
low quiescent current and fast transient response. It
guarantees delivery of 300mA output current and
supports preset output voltages ranging from 0.8V to
4.5V with 0.05V increment.
Based on its low quiescent current consumption, the
EMP8733 is ideal for battery-powered applications. The
high power supply rejection ratio of the EMP8733 holds
well for low input voltages typically encountered in
battery-operated systems. The regulator is stable with
small ceramic capacitive loads (1µF typical). The
EMP8733 is Available in miniature 3-pin SOT-23-3
package.
EMP products are Halogen free and RoHS compliant.
Features
„ 300mA guaranteed output current
„ 62dB typical PSRR at 1kHz
„ 110µV RMS output voltage noise (10Hz to 100kHz)
„ 290mV typical dropout at 300mA
„ 57µA typical quiescent current
„ Fast line and load transient response
„ 2.2V to 5.5V input range
„ Stable with small ceramic output capacitors
„ Over temperature and over current protection
„ ±2% output voltage tolerance
Applications
„ Wireless handsets
„ PCMCIA cards
„ DSP core power
„ Hand-held instruments
„ Battery-powered systems
„ Portable information appliances
Typical Application
*Use 2.2μF for VOUT < 1.2V

Note 1: Absolute Maximum ratings indicate limits beyond which damage may occur. Electrical specifications do not
apply when operating the device outside of its rated operating conditions.
Note 2: All voltages are with respect to the potential at the ground pin.
Note 3: Condition does not apply to input voltages below 2.2V since this is the minimum input operating voltage.
Note 4: Dropout voltage is measured by reducing VIN until VOUT drops 100mV from its nominal value at VIN -VOUT = 1V.
Dropout voltage does not apply to the regulator versions with VOUT less than 2.2V.
