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

Verify the specific output voltage code '2J' corresponds to 2.95 V as per the manufacturer's naming convention. Confirm the 'M5T1' suffix indicates the SOT-23-5 package with tape-and-reel packing. Ensure compatibility with ceramic capacitors of 1.0 μF or more for stable operation.

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

Select this component when a fixed 2.95 V output is required from a 2.0 V to 5.5 V input source. Consider the S-13R1A type specifically for its discharge shunt and constant current source pull-down functions. Evaluate thermal dissipation requirements if operating near maximum load currents.

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

This part belongs to the S-13R1 Series developed by ABLIC Inc. using CMOS technology. The series is characterized by ultra-low current consumption and high accuracy. It is designed for applications requiring reliable voltage regulation with minimal standby power drain.

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

Substitutes must match the SOT-23-5 package and provide similar 150 mA output current capabilities. Verify that replacement parts support the same input voltage range and include reverse current protection features to maintain system integrity.

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

What is the function of the NC pin on the SOT-23-5 package?

The NC pin is electrically open. It can be connected to the VIN pin or the VSS pin if necessary, but it does not serve an active function.

How does the reverse current protection work?

The internal detection circuit monitors the voltage difference between VIN and VOUT. If VOUT exceeds VIN beyond a specific threshold, the circuit switches the connection direction of the parasitic diode to prevent reverse current flow.
