S-1315C1J-A6T2U3

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

The S-1315C1J-A6T2U3 is a CMOS linear voltage regulator from the S-1315 Series, manufactured by ABLIC Inc. It provides a fixed output voltage of 1.0 V with an accuracy of ±15 mV. The device supports an input voltage range of 1.4 V to 5.5 V and delivers up to 200 mA of output current. Key electrical parameters include a typical dropout voltage of 0.844 V at full load, operation current of 7 μA typ., and power-off current of 0.1 μA typ. It features built-in overcurrent protection and an ON/OFF control pin. The component is housed in an HSNT-6 (1212) package.

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

Verify the specific product type suffix 'C' to confirm the presence of the constant current source pull-down function and absence of the discharge shunt function. Ensure the package designation matches the required footprint. Confirm compliance with RoHS and halogen-free requirements as specified in the datasheet. Check for any design life cycle notices regarding new design recommendations.

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 C-type variant is suitable when internal pull-down on the ON/OFF pin is desired but rapid discharge shunting is not required. Consider the thermal dissipation characteristics of the HSNT-6 package under maximum load conditions. Verify that the input voltage remains within the specified operating range to ensure proper regulation.

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

This part belongs to the S-1315 Series of positive voltage regulators developed using CMOS technology. The series offers selectable output voltages from 1.0 V to 4.2 V in 0.05 V steps. The S-1315C type specifically integrates a constant current source pull-down while omitting the discharge shunt function found in other variants like the A or B types.

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

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

For the S-1315 Series C type, the ON/OFF pin is internally pulled down to the VSS pin when floating, setting the VOUT pin to the VSS level.

Is an output capacitor required for stability?

No, an output capacitor is unnecessary for phase compensation. Operation is stabilized even without one, though a ceramic capacitor of 10 μF or less may be used if needed.
