S-13R1E30-A4T2U3

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

The S-13R1E30-A4T2U3 is a CMOS low-dropout voltage regulator manufactured by ABLIC Inc. It provides a fixed output voltage of 3.0 V with a maximum output current capability of 150 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and features a typical power supply rejection ratio (PSRR) of 70 dB. It maintains a low quiescent current of 5 uA and ensures stable performance across a wide operating temperature range from -40°C to +85°C. The component utilizes the HSNT-1010-4 surface-mount package.

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

Verify the specific suffix codes against official ABLIC documentation to confirm pin configuration and tolerance levels. Ensure compatibility with the target PCB footprint, specifically the HSNT-1010-4 package dimensions. Cross-reference thermal dissipation requirements with system load conditions to prevent overheating. Confirm RoHS compliance status if required by regional regulations before finalizing procurement orders.

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

Select this component when a fixed 3.0 V output is required with minimal static power consumption. The 150 mA current rating suits moderate load applications without excessive heat generation. Consider the 70 dB PSRR for environments with noisy power supplies. Verify that the input voltage remains above the minimum dropout threshold under all operating conditions to maintain regulation stability.
