EUP7913/A
300mA Low-Noise LDO
Without Bypass Capacitor
DESCRIPTION
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.
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.
FEATURES
z 2.5V to 5.5V Input Voltage Range
z 30µV(rms) Output Noise
z 200mV Dropout @ 300mA
z 70dB PSRR at 1kHz No Bypass Capacitor
z Low 30µA Ground Current
z Guaranteed 300mA Output Current
z Stable with a 1µF Ceramic Output Capacitor When
VOUT 1.5V, or 2.2µF when VOUT<1.5V
z Excellent Load/Line Transient
z Thermal Shutdown and Current Limit
Protection
z Available 1.2V to 3.6V fixed output voltages
(50mV increments)
z Space-Saving SOT23-3 & SOT23-5 Package
z RoHS Compliant and 100% Lead (Pb)-Free
APPLICATIONS
z Cellular Phones
z Camera Modules
z PDA and Palmtop Computers
z Consumer/Personal Electronics
