onsemi Voltage Regulators - Linear FAN2564UC25X

The FAN2564UC25X is a linear voltage regulator designed for digital applications, providing a fixed output voltage of 2.5V with a guaranteed output current of 300mA. It operates with a minimum input voltage of 1.65V and supports a maximum input voltage of 3.6V. The device features a low dropout voltage of 100mV at 300mA, making it suitable for applications requiring efficient voltage regulation. This regulator is characterized by a high initial output voltage accuracy of ±1% and a low quiescent current of 45µA at no load. It also offers low output noise of 100µV RMS and a power supply rejection ratio (PSRR) of 60dB at 1kHz, ensuring stable performance in sensitive electronic environments. The enable pin allows for shutdown mode, reducing operating current to approximately 10nA. The FAN2564UC25X is designed to be stable with small ceramic capacitors, facilitating space-saving designs. It is available in a compact 4-bump wafer-level chip-scale package (WLCSP) and a 6-lead ultra-thin molded leadless package (UMLP), making it suitable for applications in cell phones, smartphones, WLAN, and portable media players.
