S-13R1G12-M5T1U3

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

The S-13R1G12-M5T1U3 is a CMOS voltage regulator from the ABLIC S-13R1 series, designed for low-power applications. It provides a fixed output voltage of 1.2 V with a maximum output current of 150 mA. The device operates within an input voltage range up to 5.5 V and features a typical power supply rejection ratio (PSRR) of 70 dB at 1 kHz. Key electrical parameters include a maximum dropout voltage of 880 mV at 100 mA, a line regulation of 0.05 %/V, and a load regulation of 25 mV. It supports a junction temperature range from -40°C to +85°C and includes protection against overcurrent, reverse current, and thermal shutdown.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated reverse current protection mechanism prevents backflow from output to input.
• Built-in thermal shutdown circuitry protects the device from overheating under fault conditions.
• Overcurrent protection limits output current to safeguard connected loads and the regulator itself.

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

• Battery-powered portable electronic devices requiring ultra-low quiescent current
• Wireless communication modules and sensors in IoT networks
• Microcontroller system power supplies in consumer electronics

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

Verify the specific suffix M5T1U3 against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SC-82AB/SOT-343 package. Confirm that the fixed 1.2 V output aligns with target circuit requirements before procurement.

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

Select this component when a stable 1.2 V rail is needed with minimal static power consumption. The 150 mA output capability suits moderate load currents. Verify that the 5.5 V maximum input voltage exceeds the highest expected source voltage. Consider the SC-82AB package size constraints during layout planning.

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

This part belongs to the S-13R1 series of low-dropout regulators characterized by ultra-low quiescent current. It is manufactured by ABLIC Inc., a specialist in precision analog and mixed-signal ICs. The series is engineered for battery-operated systems where extending operational life is critical.

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

Direct substitutes must match the 1.2 V fixed output, 150 mA current rating, and SOT-343/SC-82AB package. Verify pinout compatibility and thermal characteristics. Cross-reference with other ABLIC S-13R1 variants or equivalent LDOs from other manufacturers ensuring identical electrical performance and protection features.
