EUP7981

150mA Low-Noise LDO in SC-70

DESCRIPTION

FEATURES

Space-Saving 5-pin SC-70 Package

2.5V to 5.5V Input Voltage Range

50µV(rms) Output Noise

140mV Dropout @ 150mA

75dB PSRR at 1kHz

Low 70µA Ground Current

150mA Output Current

The EUP7981 is an efficient, CMOS voltage regulator

optimized for ultra-low-noise applications. It offers

high output accuracy, extremely low dropout voltage

low ground current and fast start-up time.

The EUP7981 provides a very low noise output, ideal

for RF applications where a clean voltage source is

required. A noise bypass pin is also available for

further reduction of output noise.

Designed specifically for handheld and battery-

Stability with 1µF Ceramic Output Capacitors

Excellent Load/Line Transient

powered devices, the EUP7981 provides

TTL-logic-compatible enable pin. When disabled,

power consumption drops nearly to zero.

Thermal Shutdown and Current Limit

The EUP7981 also works with low-ESR ceramic

capacitors, reducing the amount of board space

necessary for power applications, critical in handheld

wireless devices.

Protection

Available in 1.5V,1.8V,1.85V,2.5V,2.8V,2.85V,

3.0V ,3.3V and Adjustable Voltages

RoHS Compliant and 100% Lead (Pb)-Free

Available in the SC-70 package, the EUP7981 offers a

wide range of output voltages. Key features include

current limit, thermal shutdown and faster transient

response.

APPLICATIONS

Cellular Phones

Bluetooth Portable Radios and Accessories

PDA and Palmtop Computers

Consumer/Personal Electronics
