SG7915K-883B

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The SG7915K-883B is a negative fixed linear voltage regulator manufactured by Microchip Technology. It provides a stable -15 V output with a maximum load current of 1.5 A. The device operates within an input voltage range up to -30 V and supports a wide temperature range from -55 °C to +150 °C. Key electrical specifications include a line regulation of 120 mV and a load regulation of 120 mV. The quiescent current is specified at 3 mA. It utilizes a TO-3-3 package for surface mount or through-hole installation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix K against official Microchip documentation to confirm package type and compliance status. Confirm that the -883B designation aligns with required military reliability standards. Check for recent Product Change Notifications (PCN) regarding manufacturing site changes. Ensure compatibility with existing board layouts for the TO-3-3 form factor before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a negative voltage rail is required alongside a positive counterpart like the SG78xx series. The TO-3-3 package offers robust thermal performance suitable for high-current applications. Consider the -15 V output specifically for analog circuit biasing or operational amplifier supplies in harsh environments where standard commercial regulators may fail.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the SG79xx family of negative fixed voltage regulators. It serves as the complementary counterpart to the SG78xx positive regulator series. The -883B suffix indicates adherence to MIL-PRF-38534 or similar high-reliability specifications, distinguishing it from standard commercial variants.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Official substitutes include other SG7915 variants with compatible pinouts such as SG7915IG-883B or SG7915T-883B, provided the package style matches the design requirements.
