Linear & Switching Voltage Regulators

LDL1117S30R Description

The LDL1117S30R from STMicroelectronics is a high-performance, fixed-output linear voltage regulator designed to deliver a stable 3V output at up to 1.2A of continuous current. With a wide input voltage range of up to 18V, this regulator is engineered for robustness and efficiency, featuring a low dropout voltage of 0.6V (max) at 1.2A, making it ideal for applications where input voltage headroom is limited. The device operates with a quiescent current of 500 µA, ensuring minimal power loss in standby modes. Packaged in a SOT-223 surface-mount form factor, it is suitable for space-constrained designs and is available in Tape & Reel (TR) for automated assembly.

LDL1117S30R Features

• Fixed 3V Output: Precision-regulated voltage for stable power delivery.
• High Current Capability: Supports up to 1.2A with over-current and thermal protection for enhanced reliability.
• Low Dropout Voltage: 0.6V (max) at 1.2A ensures efficient operation even with low input voltages.
• Excellent PSRR: 87dB to 65dB (120Hz–100kHz) minimizes noise in sensitive applications.
• Robust Protection: Includes UVLO (Under Voltage Lockout), over-temperature, and over-current safeguards.
• Wide Input Range: Accepts up to 18V, accommodating various power sources.
• Low Quiescent Current: 500 µA reduces power consumption in idle states.
• RoHS3 & REACH Compliant: Meets stringent environmental standards.
