78M15

Voltage Regulators - Linear Regulator Controllers Overview

The SL78M15 is a fixed positive linear voltage regulator manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It provides a stable 15 V output with a maximum continuous current capability of 1 A. The device accepts an input voltage range from 17 V to 25 V and operates reliably within a temperature range of -20°C to +150°C. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 80 dB at 120 Hz, a maximum dropout voltage of 2 V at 500 mA, and a maximum quiescent operating current of 8 mA.

Voltage Regulators - Linear Regulator Controllers Feature Summary

• Integrated thermal overload shutdown protection for enhanced reliability under high-temperature conditions.
• Built-in short circuit current limiting to safeguard the component during fault conditions.
• Output transistor safe operating area (SOA) protection ensures stability across varying load profiles.

Voltage Regulators - Linear Regulator Controllers Applications

• High efficiency linear regulation in power supply circuits
• Post-regulation filtering for switching power supplies
• Dedicated power supply modules for microprocessor systems
• Voltage regulation stages in motherboard designs

Voltage Regulators - Linear Regulator Controllers Procurement Notes

Verify that the ordered part number matches the specific manufacturer designation for the 1 A variant. Confirm package type compatibility with your PCB footprint. Ensure the supplier provides documentation confirming RoHS compliance status. Validate that the component meets the required operating temperature range for your specific application environment before finalizing procurement.

Voltage Regulators - Linear Regulator Controllers Selection Notes

Select this component when a fixed 15 V output is required with up to 1 A load capacity. It is suitable for applications needing robust internal protection features such as thermal shutdown and short-circuit limiting. Consider the 2 V dropout voltage at lower currents when designing input voltage margins. This regulator is appropriate for general-purpose linear regulation where moderate ripple rejection is sufficient.

Voltage Regulators - Linear Regulator Controllers Part Context

This component belongs to the SL78xx series of positive voltage regulators produced by Slkor. The series offers various fixed output voltages including 5 V, 6 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, and 24 V. These devices are designed as direct replacements for standard industry equivalents, providing reliable performance in compact through-hole packages like TO-220.

Voltage Regulators - Linear Regulator Controllers Replacement Considerations

Standard industry equivalents such as the MC78M15 or LM78M15 may serve as functional substitutes. Verify pinout compatibility and thermal characteristics before swapping. Ensure the replacement part supports the same 1 A output current and 15 V fixed output requirement. Check that the alternative component meets the same safety certification standards.
