DESCRIPTION
The EUP7913/A 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 EUP7913/A 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 EUP7913/A provides a TTL-logic-compatible enable pin. When the EUP7913/A is disabled, power consumption drops nearly to zero. Key features include current limit, thermal shutdown and faster transient response.
