S-13R1G19-N4T1U3

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

The S-13R1G19-N4T1U3 is a CMOS low dropout (LDO) voltage regulator manufactured by ABLIC Inc. It provides a fixed output voltage of 1.9 V with a maximum continuous output current of 150 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and features ultra-low quiescent current consumption, typically 1 µA. Key electrical characteristics include a typical power supply rejection ratio (PSRR) of 70 dB at 1 kHz and a maximum dropout voltage of 0.88 V at 100 mA load. The unit offers high voltage regulation accuracy of ±1% and includes built-in protection functions such as overcurrent protection, thermal shutdown, and reverse current protection.

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

Verify the specific suffix codes against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with surface-mount assembly processes for the SC-82AB package. Cross-reference RoHS compliance status with the latest manufacturer environmental declarations prior to final procurement approval.

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

Select this component when a fixed 1.9 V rail is required with strict limits on static power consumption. The 150 mA output capability suits moderate load scenarios where standard LDOs would cause excessive heat dissipation. Verify that the minimum input voltage remains above the dropout threshold under all expected load conditions to maintain stable regulation.

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

This part belongs to the S-13R1 series of ABLIC's voltage regulator portfolio. The series is characterized by its inclusion of reverse current protection, distinguishing it from earlier generations like the S-1313. It utilizes the compact SC-82AB surface-mount package, designed for space-constrained printed circuit board layouts in modern consumer and industrial electronics.

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

Direct substitutes within the same series include S-13R1G18-N4T1U3 (1.8 V) and S-13R1G20-N4T1U3 (2.0 V), provided the system design tolerates minor voltage deviations. Other series such as S-1313 lack reverse current protection and are not electrically equivalent.
