EUP7917
300mA, High PSRR Low-Noise LDO
DESCRIPTION
The EUP7917 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 EUP7917 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-
powered devices, the EUP7917 provides a
TTL-logic-compatible enable pin. When disabled,
power consumption drops nearly to zero.
The EUP7917 also works with low-ESR ceramic
capacitors, reducing the amount of board space
necessary for power applications, critical in handheld
wireless devices.
Available in the SC-70 and SOT23-5 package, the
EUP7917 offers a wide range of output voltages. Key
features include current limit, thermal shutdown and
faster transient response.
