S-1167B20-M5T1U

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

The S-1167B20-M5T1U is a positive fixed-output CMOS voltage regulator from the S-1167 series, manufactured by ABLIC Inc. It provides a nominal output voltage of 2.0 V with an accuracy of ±1.0%. The device supports a maximum input voltage range of 2.0 V to 6.5 V and can deliver up to 150 mA of output current. Key electrical characteristics include a typical dropout voltage of 0.23 V at 100 mA, a ripple rejection ratio of 70 dB at 1 kHz, and ultra-low current consumption of 9 µA during operation. It features built-in overcurrent protection and an ON/OFF control circuit.

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

Verify that the ordering suffix M5T1U corresponds to the SOT-23-5 package with tape packing and lead-free (Sn 100%), halogen-free environmental compliance. Confirm the 'B' product type indicates positive logic for the ON/OFF pin. Ensure application conditions respect the package power dissipation limits when operating near maximum output currents.

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

Select this component when a precise 2.0 V rail is required with minimal quiescent current draw. The positive logic ON/OFF pin allows direct interfacing with standard high-level control signals. Verify that the input voltage remains within the 2.0 V to 6.5 V range and that external capacitor values meet the stability requirements specified in the datasheet.

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

This part belongs to the S-1167 Series, a family of low-dropout regulators designed for portable electronics. The series utilizes CMOS technology to achieve high accuracy and low power consumption. The B-type designation specifically denotes positive logic control for the enable pin, distinguishing it from the A-type negative logic variant within the same package footprint.
