The CXLD64288 is a low-power, low-noise, low-dropout, CMOS linear voltage regulator that operates from a 2.5V to 5.5V input voltage.
The CXLD64288 is the perfect choice for low voltage, low power applications. A low ground current makes this part attractive for battery operated power systems. The CXLD64288 also offers ultra low dropout voltage to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the CXLD64288’s ultra low output noise (30μVRMS) and high PSRR. An external noise bypass capacitor connected to the device’s BP pin can further reduce the noise level.
Other features include a 110kΩ pull down resistor at EN pin, current limit and thermal shutdown protection.
The CXLD64288 is available in Green UTDFN-1.6×1.6-6L and TDFN-2×2-6L packages. It operates over an ambient temperature range of -40℃ to +85℃
