XB2204-ADJ – LDO Regulator – Xinluda

The XB2204-ADJ is an adjustable-output, low-dropout (LDO) linear voltage regulator from Xinluda in a compact SOT-23-5 package, supporting a wide input voltage range of 2.6V to 24V with an enable control input, current limiting, and thermal shutdown protection.

The XB2204-ADJ from Xinluda Information Technology Co., Ltd. is the adjustable-output member of the XB2204 family of positive, low-dropout (LDO) linear voltage regulators, fabricated on a high-voltage EPNP process. Housed in a space-saving SOT-23-5 package, the device accepts a wide operating input voltage range of 2.6V to 24V, making it well suited to USB-powered, battery-powered, and general-purpose point-of-load applications where a clean, low-noise regulated rail is required. The “-ADJ” suffix denotes the externally adjustable output version, with the output voltage set by a simple external resistor divider according to V_OUT = V_REF (1 + R1/R2) using the internal 1.24V reference; fixed-output variants such as the XB2204-3.3 and XB2204-5.0 are also offered within the same family.
