EUP7913/A

300mA Low-Noise LDO

Without Bypass Capacitor

DESCRIPTION

FEATURES

The EUP7913/A 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 EUP7913/A 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 EUP7913/A provides a

TTL-logic-compatible enable pin. When the

EUP7913/A 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

200mV Dropout @ 300mA

70dB PSRR at 1kHz No Bypass Capacitor

Low 30µA Ground Current

Guaranteed 300mA 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 EUP7913/A works with low-ESR ceramic

capacitors. Available in the SOT23-3 or SOT23-5

space saving package which reduces the amount of

board space necessary for power applications. The

EUP7913/A offers wide fixed output voltage versions.

Available 1.2V to 3.6V fixed output voltages

(50mV increments)

Space-Saving SOT23-3 & SOT23-5 Package

RoHS Compliant and 100% Lead (Pb)-Free

APPLICATIONS

Cellular Phones

Camera Modules

PDA and Palmtop Computers

Consumer/Personal Electronics
