It offers high output accuracy, extremely low dropout voltage, low ground current and fast start-up time. The CXLD64240 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 CXLD64240 provides a TTL-logic-compatible enable pin. When the CXLD64240 is disabled, power consumption drops nearly to zero. Key features include current limit, thermal shutdown and faster transient response. The CXLD64240 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 ECXLD64240offers wide fixed output voltage versions.
