EUP7914

150mA Low-Noise LDO in SC-82

Without A Bypass Capacitor

DESCRIPTION

FEATURES

The EUP7914 is an efficient CMOS low dropout (LDO)

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 EUP7914 provides a very low noise

output without a bypass capacitor, ideal for RF

applications where a clean supply voltage source is

required. Specifically designed for handheld and

battery-powered devices, the EUP7914 provides a

TTL-logic-compatible enable pin. When the EUP7914

is disabled, power consumption drops nearly to zero.

Key features include current limit, thermal shutdown

and faster transient response.

2.5V to 5.5V Input Voltage Range

30µV(rms) Output Noise

90mV Dropout @ 150mA

70dB PSRR at 1kHz No Bypass Capacitor

Low 30µA Ground Current

Guaranteed 150mA Output Current

Stable with a 1µF Ceramic Output Capacitor when

V_OUT1.5V, or 2.2µF when V_OUT<1.5V

≥

Excellent Load/Line Transient

Thermal Shutdown and Current Limit

Protection

The EUP7914 works with low-ESR ceramic capacitors.

Available in the SC-82 space saving package which

reduces the amount of board space for power

applications. The EUP7914 offers wide fixed output

voltage versions.

Available 1.2V to 3.6V Fixed Output Voltages

(50mV increments)

Space-Saving 4-pin SC-82 Package

RoHS Compliant and 100% Lead (Pb)-Free

APPLICATIONS

Cellular Phones

Camera Modules

PDA and Palmtop Computers

Consumer/Personal Electronics
