EUP7965 Datasheet | Eutech Microelectronics

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 65d B at low frequencies. High power supply rejection is maintained down to low input voltage levels mon 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.
