S-L2980A53MC-TF-G

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

The S-L2980A53MC-TF-G is a fixed positive CMOS voltage regulator from the S-L2980 series, providing a nominal output of 5.3 V with ±2.0% accuracy. It operates within an input voltage range of 2.0 V to 10 V and delivers up to 150 mA output current. The device features a typical dropout voltage of 110 mV at 50 mA and maintains low current consumption of 90 μA during operation. It includes a built-in ON/OFF circuit for power management and supports ceramic output capacitors.

• Power supply for home electric appliances
• Power supply for cellular phones

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

Verify the specific environmental code suffix required for your assembly process. The 'G' suffix indicates lead-free specifications; confirm if halogen-free requirements necessitate the 'U' suffix instead. Ensure the ordering part number matches the exact output voltage and logic type defined in the manufacturer's product name structure table to avoid functional mismatches.

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

Select this component when a precise 5.3 V rail is needed with minimal voltage drop. Verify that the application load does not exceed the package power dissipation limits, especially at higher ambient temperatures. Confirm that the input voltage remains within the specified 2.0 V to 10 V range and that the output capacitor meets the minimum capacitance and ESR requirements for stability.

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

This device belongs to the S-L2980 series of high ripple-rejection and low dropout CMOS voltage regulators manufactured by ABLIC Inc. The series offers various fixed output voltages selectable in 0.1 V steps from 1.5 V to 6.0 V. All variants share the same SOT-23-5 package and core electrical characteristics, differing primarily in their internal feedback resistor ratios to set the specific output voltage.

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

Other S-L2980 series parts with different output voltages (e.g., S-L2980A50MC-TF-G for 5.0 V) are pin-compatible but provide different regulated outputs. Substituting requires verifying that the new voltage level meets the load requirements. Direct replacements with identical 5.3 V output are limited to other manufacturers' LDOs with matching pinouts and electrical specs.
