TLV70433DBVR Low-Dropout Linear Regulator

Specifications

Product Overview

The TLV70433DBVR is a Texas Instruments low-dropout linear regulator for Power_Management designs requiring up to 150 mA output current. Recommended operating conditions specify a 2.5 to 24 V input range, a 1.205 to 5 V recommended output voltage range, and -40°C to +125°C operating junction temperature.

The regulator is supplied in the DBV SOT-23 5-pin package with a 2.90 mm × 1.60 mm body. Pin functions are GND on pin 1, IN on pin 2, OUT on pin 3, and NC on pins 4 and 5. The NC pins are not internally connected and may be left open or tied to ground for improved thermal performance.

Electrical characteristics include ±2% DC output accuracy at TJ = 25°C, 3.4 µA typical quiescent current at 100 mA load, and dropout voltage values of 75 mV at 10 mA, 400 mV at 50 mA, and 850 mV typical at 100 mA. The device requires output capacitance for stability and includes overcurrent protection plus internal soft-start.

Procurement Notes

When requesting a quote for TLV70433DBVR, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.

If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.

For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
