DESCRIPTION
The EUP7965 is designed for portable and wireless
applications with demanding performance and space
requirements.
The EUP7965 is stable with a small 1µF ±30% ceramic
output capacitor. The EUP7965’s performance is
optimized for battery powered systems to deliver low
noise, low dropout voltage, low quiescent current and
excellent line and load transient response.
An optional external bypass capacitor reduces the
output noise further without slowing down the load
transient response. Power supply rejection is better
than 65dB at low frequencies. High power supply
rejection is maintained down to low input voltage
levels common to battery operated circuits. Other
features include a logic-controlled shutdown mode,
short-circuit and thermal-shutdown protection. The
EUP7965 is available in a SOT23-5,SOT23-6 package.
