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

Verify the specific ordering suffix U5T1G against official documentation to confirm package type and environmental compliance. Confirm the product status as active or obsolete before procurement. Ensure the selected variant matches the required output voltage and logic level for the ON/OFF pin. Cross-reference the manufacturer's datasheet for any recent design changes or end-of-life notices.

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

Select this component for applications requiring a fixed 2.3 V output with low quiescent current. Ensure the input voltage remains within the 2.0 V to 6.5 V range. Verify that the load current does not exceed 300 mA and consider package power dissipation limits at higher currents. Use ceramic capacitors with ESR of 2.0 Ω or less for stability.

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

This part belongs to the S-1132 Series, which offers various output voltages selectable in 0.1 V steps. The series includes different packages such as SOT-23-5, SOT-89-5, and SNT-6A(H).

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

What is the logic level for the ON/OFF pin on the S-1132B23-U5T1G?

The 'B' in the part number indicates positive logic, meaning the regulator is enabled when the ON/OFF pin is set to a high level and disabled when set to a low level.

Can the S-1132B23-U5T1G operate with only a ceramic capacitor?

Yes, the device is designed to operate stably with a ceramic capacitor of 0.1 μF or more on both the input and output pins, provided the ESR is 2.0 Ω or less.
