S-13R1H29-I4T1U3

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

The S-13R1H29-I4T1U3 is a CMOS linear voltage regulator from the S-13R1 series manufactured by ABLIC Inc. It provides a fixed output voltage of 2.9 V with a maximum output current of 150 mA. The device operates within an input voltage range of 2 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 70 dB. It includes reverse current protection, overcurrent protection, and thermal shutdown. The component is housed in an SC-82AB package and supports surface mount installation.

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

• Integrated reverse current protection prevents backflow when input voltage drops below output voltage.
• Built-in overcurrent protection and thermal shutdown circuits ensure operational safety under fault conditions.
• High power supply rejection ratio effectively suppresses ripple and noise from the input source.

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

• Battery-powered portable electronic devices requiring low quiescent current
• Embedded systems needing stable 2.9 V logic supply rails
• Industrial control modules operating in wide temperature environments

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

Verify the specific suffix I4T1U3 against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with SC-82AB footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement orders.

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

Select this component for applications requiring a fixed 2.9 V output with 150 mA capability. Consider the SC-82AB package size constraints and the 2 V minimum input voltage requirement. Evaluate thermal performance based on expected load currents and ambient operating temperatures within the -40°C to +85°C range.
