TLV70731DQNT

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

The TLV70731DQNT is a fixed-output low-dropout (LDO) voltage regulator from Texas Instruments, designed for portable devices. It provides a fixed output voltage of 3.1 V with a maximum output current of 200 mA. The device features a typical quiescent current of 25 uA and a typical power supply rejection ratio (PSRR) of 50 dB. It operates within an input voltage range of 2 V to 5.5 V and has a maximum dropout voltage of 0.25 V at full load. The component supports surface-mount installation in a 4-X2SON package and functions across a temperature range of -40 C to +125 C.

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

Verify the specific output voltage designation within the part number to ensure it matches the required 3.1 V specification. Confirm the X2SON-4 package variant aligns with PCB footprint constraints. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure thermal management strategies account for the small form factor during operation.

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

Select this regulator when a fixed 3.1 V rail is necessary with minimal static power consumption. Consider the 200 mA current limit for load requirements. Evaluate the 50 dB PSRR against noise sensitivity needs. Compare the 0.25 V dropout against available headroom between input and output voltages under load conditions.
