S-13R1D30-M5T1U3

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

The S-13R1D30-M5T1U3 is a CMOS positive voltage regulator with a fixed 3.0 V output and 150 mA current capacity. It operates within an input voltage range of 2.0 V to 5.5 V and features a typical dropout voltage of 150 mV at 100 mA. The device consumes 5 μA during operation and 0.1 μA when powered off. It includes reverse current protection, overcurrent protection, and thermal shutdown circuits.

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

Verify the specific suffix M5T1U3 corresponds to the SOT-23-5 package and tape-and-reel configuration. Confirm that the D-type designation matches the required absence of discharge shunt and pull-down functions for the target application design.

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

Select this component for applications requiring low quiescent current and reverse current blocking without external diodes. Ensure the load current does not exceed 150 mA and verify that the package power dissipation limits are respected under maximum ambient temperature conditions.

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

This part belongs to the S-13R1 series developed by ABLIC Inc. utilizing CMOS technology. The series provides high-accuracy output voltages selectable in 0.05 V steps. The D-type variant specifically lacks internal discharge and pull-down circuits on the ON/OFF pin.

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

Does the S-13R1D30-M5T1U3 require an external protection diode?

No, the built-in reverse current protection function controls reverse current to a maximum of 0.09 μA, eliminating the need for an external IC protection diode.

What is the behavior of the ON/OFF pin for the D-type product?

The D-type product has neither a discharge shunt function nor a constant current source pull-down. The pin should not be left floating; connect it to VIN if unused.
