S-13R1E22-M5T1U3

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

The S-13R1E22-M5T1U3 is a positive fixed linear voltage regulator from the ABLIC S-13R1 series. It provides a fixed output voltage of 2.2 V with a maximum output current of 150 mA. The device operates within an input voltage range of 2.0 V to 5.5 V and features a typical dropout voltage of 280 mV at 100 mA load. It utilizes a SC-74A (SOT-753) surface-mount package. The component supports operation across a temperature range of -40°C to +85°C and includes reverse current protection capabilities.

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

• Integrated reverse current protection prevents backflow when input voltage drops below output voltage
• Low dropout characteristic ensures stable regulation under minimal input-output voltage differentials
• Fixed output voltage configuration eliminates external resistor requirements for standard setpoints

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

• Battery-powered portable electronics requiring efficient power management
• Embedded systems needing stable low-voltage rails for microcontrollers
• Communication modules operating within specified input voltage limits

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 SC-74A footprint requirements during PCB layout. Confirm thermal performance expectations relative to ambient conditions and board copper area, as thermal dissipation impacts reliability in high-current scenarios.

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

Select this component when a fixed 2.2 V rail is required with moderate current demands up to 150 mA. The S-13R1 series is suitable for applications prioritizing reverse current protection over ultra-low quiescent current found in other ABLIC lines. Compare dropout voltage specifications against minimum input supply levels to ensure adequate headroom under all operating conditions.

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

This part belongs to the S-13R1 family of CMOS LDO regulators designed by ABLIC Inc. The series emphasizes compact packaging and integrated protection features for space-constrained designs. Unlike higher-current variants in the S-13A1 series or lower-power S-1318 series, this model balances current capability with low quiescent current consumption.

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

Direct substitutes include other S-13R1 series parts with compatible output voltages and packages, such as S-13R1D13-M5T1U3 for 1.3 V output. Verify pinout compatibility and thermal characteristics before substituting with non-series regulators.
