S-1167B50-I6T2G

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

The S-1167B50-I6T2G is a positive voltage regulator from the S-1167 Series, manufactured by ABLIC Inc. It provides a fixed output voltage of 5.0 V with an accuracy of ±1.0%. The device operates within an input voltage range of 2.0 V to 6.5 V and supports an output current of up to 150 mA. Key electrical parameters include a typical dropout voltage of 0.21 V at 100 mA, a typical current consumption of 9 µA during operation, and a ripple rejection of 70 dB at 1.0 kHz. It utilizes a low on-resistance P-channel MOSFET output transistor.

• Constant-voltage power supply for portable equipment

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

Verify the environmental code suffix 'G' against official documentation, as it indicates lead-free specifications distinct from the standard 'U' variant. Confirm package type SNT-6A(H) compatibility with PCB land patterns. Ensure input and output capacitors meet the minimum 1.0 µF ceramic requirement with equivalent series resistance of 1.0 Ω or less for stable operation.

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

Select this component when a fixed 5.0 V output is required with high accuracy and minimal quiescent current. The B-type designation ensures positive logic control for the ON/OFF pin. Consider thermal dissipation limits if operating near maximum load currents, as power dissipation depends on package mounting conditions. Verify that the input voltage remains within the 2.0 V to 6.5 V range under all operating conditions.

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

This part belongs to the S-1167 Series of CMOS voltage regulators designed for portable applications. The series offers selectable output voltages in 0.1 V steps from 1.5 V to 5.5 V. The S-1167B50-I6T2G specifically uses the SNT-6A(H) package, which is an ultra-compact form factor suitable for space-constrained designs requiring high reliability and low power consumption.

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

S-1167B50-M5T1x variants offer identical electrical performance but utilize the SOT-23-5 package instead of SNT-6A(H). Other S-1167Bxx-I6T2G parts provide different fixed output voltages while maintaining the same package and feature set.
