S-11L10B32-I6T2U

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

The S-11L10B32-I6T2U is a positive fixed-output linear voltage regulator from the ABLIC S-11L10 series, manufactured using CMOS technology. It provides a fixed output voltage of 3.2 V with an accuracy of ±1.0%. The device supports a maximum output current of 150 mA and operates within an input voltage range of 1.2 V to 3.65 V. Typical current consumption during operation is 9 μA, while power-off consumption is 0.1 μA. It features a typical dropout voltage of 210 mV at 100 mA and includes built-in overcurrent protection and an ON/OFF control circuit. The component is housed in an SNT-6A(H) surface-mount package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Built-in discharge shunt function that actively discharges output capacitance when the ON/OFF pin is set to the OFF level.
• Constant current source pull-down feature available for the B-type product, allowing internal connection to the ground pin.
• Compatible with small ceramic capacitors of 1.0 μF or more for both input and output stabilization.
• Integrated overcurrent protection circuit limits output current to protect against short circuits.

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

Verify the specific suffix I6T2U corresponds to the SNT-6A(H) tape packaging format as defined in the manufacturer's naming convention. Confirm compliance with RoHS3 and halogen-free requirements by checking the environmental code U on the component marking. Ensure the design accounts for the NOT RECOMMENDED FOR NEW DESIGN status indicated in the official documentation before finalizing procurement plans.

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

Select this component for applications requiring low quiescent current and high output voltage accuracy. The B-type designation ensures the availability of the constant current source pull-down function. Verify that the application load does not exceed the 150 mA limit and that the input voltage remains within the 3.65 V maximum rating. Consider the thermal dissipation capabilities of the SNT-6A(H) package under expected operating conditions.

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

This part belongs to the S-11L10 Series, which offers selectable output voltages from 0.8 V to 3.3 V in 0.05 V steps. The series utilizes P-channel MOS FET output transistors to achieve low dropout characteristics. The B-type variant specifically differentiates itself through the inclusion of an internal pull-down mechanism on the ON/OFF pin, distinguishing it from the D-type which lacks this feature.

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

What is the behavior of the ON/OFF pin when left floating?

For the S-11L10B series, the ON/OFF pin is internally pulled down to the VSS pin when floating, setting the VOUT pin to the VSS level.

How does the discharge shunt function operate?

When the ON/OFF pin is set to OFF, the output transistor turns off and the discharge shunt circuit activates, forcibly discharging the output capacitor to the VSS level faster than standard regulators.
