TS2938CS50 RLG

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

The TS2938CS50 RLG is a fixed-voltage monolithic micro-power voltage regulator manufactured by Taiwan Semiconductor. It provides a nominal output of 5V with a maximum output current of 500mA in an SOP-8 package. The device features ultra-low dropout performance, typically 60mV at light load and 600mV at full load. It includes logic-controlled electronic shutdown functionality and operates within an input voltage range of up to 26V. Key electrical specifications include a quiescent current of 100µA (typical), line regulation of 0.05%, and ripple rejection of 60dB. The component is qualified under AEC-Q101 standards for automotive applications.

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

Verify the specific ordering suffix 'RLG' corresponds to the SOP-8 package and reel packing configuration as documented. Confirm RoHS compliance and halogen-free status requirements against project specifications. Ensure moisture sensitivity level 3 handling procedures are followed during assembly. Validate that the 5V output variant matches the design requirement before procurement.

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

Select this component when a fixed 5V supply with 500mA capability is required. Consider the low dropout characteristics for battery-operated designs where input voltage approaches the output level. Evaluate the need for the active-low inhibit function for system power sequencing. Verify that the SOP-8 package fits the available PCB footprint and thermal dissipation constraints.

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

This part belongs to the TS2938 series of ultra-low dropout voltage regulators from Taiwan Semiconductor. The series offers various fixed output voltages, including 3.3V and 5.0V options. All variants share the same core architecture featuring PNP output stages and integrated protection circuits. The TS2938CS50 RLG specifically denotes the 5.0V output version packaged in SOP-8.

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

TS2938CS33 RLG serves as a direct pin-compatible alternative offering a 3.3V output instead of 5.0V.
