EUP7914
150mA Low-Noise LDO in SC-82
Without A Bypass Capacitor
DESCRIPTION
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.
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.
