XB3480M3-3.3 – LDO Regulator – Xinluda

The XB3480M3-3.3 is a Xinluda fixed-output 3.3V, 100mA quasi-low-dropout linear voltage regulator in a compact SOT-23 package, pin-compatible with the industry-standard LM3480IM3-3.3.

The XB3480M3-3.3 from Xinluda is a fixed 3.3V output, 100mA quasi-low-dropout (LDO) linear voltage regulator supplied in a space-saving 3-lead SOT-23 surface-mount package. It belongs to the XB3480 family, a functional and pin-for-pin equivalent of the well-known LM3480IM3-3.3, making it a practical cross-reference for designs that need a tiny, low-cost local bias supply regulating directly from a 5V rail.

With a fixed, factory-trimmed output, minimal external component count, and a small footprint, the XB3480M3-3.3 is well suited to point-of-load regulation and powering microcontrollers, logic, and sensor sub-circuits where board area is constrained.

Key Features

• Fixed 3.3V regulated output

• Operates from input voltages up to 30V
• Compact 3-lead SOT-23 surface-mount package
• Operating temperature range -40C to +125C
• Functional / pin equivalent to LM3480IM3-3.3

Applications

• Local 3.3V bias supply from a 5V system rail
• Microcontroller and logic power
• Sensor and signal-conditioning sub-circuits
• Consumer and industrial electronics
• Battery-powered and portable equipment
