EUP7915
150mA Low-Noise LDO in SOT23-5
DESCRIPTION
The EUP7915 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 EUP7915 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 EUP7915 provides a
TTL-logic-compatible enable pin. When disabled,
power consumption drops nearly to zero.
The EUP7915 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 SOT23-5 package, the EUP7915
offers a wide range of output voltages. Key features
include current limit, thermal shutdown and faster
transient response.
