V62/03631-07XE

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

V62/03631-07XE is a military-enhanced low-dropout (LDO) voltage regulator from the TPS77633 series, manufactured by Texas Instruments. It provides a fixed 5 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 2.7 V to 10 V and maintains a typical dropout voltage of 169 mV at full load. Quiescent current is specified at 125 uA. It features fast transient response capabilities and is housed in a 20-pin HTSSOP package. The component supports an extended operating temperature range from -55°C to +125°C.

• Defense communication equipment requiring stable rail voltages
• Ruggedized embedded control modules

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

Verify the specific suffix '07XE' against official Texas Instruments documentation to confirm the exact output voltage and pin configuration, as V62 prefixes denote military lot traceability rather than functional changes. Ensure the ordering part number matches the required datasheet revision. Confirm RoHS compliance status and humidity sensitivity level prior to procurement to meet storage and handling requirements.

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

Select this component when a fixed 5 V rail is required for sensitive military electronics. The 500 mA output capability suits moderate load applications. Consider the 169 mV dropout voltage relative to the minimum input supply. The HTSSOP-20 package requires adequate thermal management for high dissipation scenarios. Verify compatibility with existing PCB footprints designed for the standard TPS77633 family.

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

This part belongs to the TPS77633 family of low-dropout regulators. The V62 prefix indicates it is a qualified military version managed through government contracting channels. It shares electrical characteristics with commercial counterparts but undergoes stricter screening and testing protocols. The device integrates internal protection mechanisms common to the series.

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

Direct replacements include other military-qualified LDOs from the same family, such as V62/03631-12XE or V62/03631-02XE, provided the output voltage matches the system requirement. Standard commercial equivalents like TPS77633QPWPR may be used if military qualification is not mandatory.
