SLKOR SL4275 (TO-252): The Ultimate High-Performance Voltage Regulator Outshining Infineon, MPS, ROHM & TI - Elevate Your Power Solutions!

 SLKOR SL4275 (TO-252) — a high-performance voltage regulator offering a superior alternative to models from Infineon, MPS, ROHM, and TI (including TLE4275, MP2014, BD42754, TLE4275-Q1, and TPS7B87-Q1).

SLKOR SL4275 — A Superior Replacement for ROHM BD42754 Linear Voltage Regulators

Product Overview:

• Input Voltage (VIN): Up to 55V
• Fixed Output Voltage (VOUT): 5.0V
• Output Current (IOUT): 800mA
• Dropout Voltage (Vdrop): 0.3V
• Package: TO-252–5

Key Benefits:

• Reliable Replacement: Designed as a high-performance, cost-effective alternative to ROHM BD42754 regulators, offering equivalent functionality and protection.
• Robust Design: The SL4275 is a monolithically integrated low-dropout voltage regulator housed in a compact 5-pin TO-252–5 package. It efficiently converts input voltages up to 55V into a stable 5.0V output.
• Enhanced Protection: Integrated undervoltage lockout (UVLO), short-circuit, and over-temperature protection ensure safe and reliable operation under abnormal conditions. A low-level reset signal is generated via the RQ pin when the output voltage drops below a typical threshold (≈4.65V), with adjustable reset delay via an external capacitor on the D pin.
• Optimized for Stability: To counteract trace effects, an input capacitor (CI) is recommended. Additionally, an output capacitor (CQ) of at least 22μF with an ESR of ≤5Ω is essential for maintaining regulation stability across a wide temperature range.
• Efficient Control Architecture: The integrated control op amp compares a reference voltage with a scaled version of the output voltage, driving a series MOS transistor via a buffer. A current-limiting control unit prevents oversaturation, ensuring optimal performance and protection.
• TTL-Compatible Inputs: With input threshold levels based on TTL standards, the SL4275 supports a wide voltage range (from -5V to 24V), ensuring stable operation even under transient overshoot conditions.

Features:

• Output Accuracy: 5V fixed output with ±2% accuracy
• Low Power Consumption: Operating current as low as 80μA
• Reset Functionality: Features power-on and brown-out reset mechanisms
• Low Dropout: Maintains efficiency with a dropout voltage of 0.3V
• Protection Mechanisms: Comprehensive short-circuit, overload, and over-temperature safeguards
• RoHS Compliant: Meets global environmental standards

The SL4275 offers a seamless, high-performance alternative for designers seeking a reliable voltage regulator solution.
