onsemi Voltage Regulators - Linear FAN2564UC13X

The FAN2564UC13X is a linear voltage regulator designed for digital applications, providing a fixed output voltage of 1.3V with a guaranteed output current of 300mA. It operates with an input voltage range of 1.65V to 3.6V and features a low dropout voltage of 100mV at full load, making it suitable for use as a post regulator in conjunction with synchronous buck converters. This regulator has a quiescent current of 45µA at no load and a low output noise of 100µV RMS, which enhances its performance in sensitive applications. The enable pin allows for shutdown mode, reducing the operating current to approximately 10nA. The FAN2564UC13X is stable with ceramic capacitors as small as 0402 case size and is available in a compact 4-bump wafer-level chip-scale package (WLCSP) with a 0.5mm pitch. It also includes thermal and short-circuit protection features, ensuring reliable operation in various conditions.
