Product Overview
TPS70933DBVR is a Texas Instruments TPS709-series fixed-output linear regulator configured for a nominal 3.3 V output. The device is categorized as a Power_Management Power_IC and is specified as a 150-mA linear voltage regulator with a recommended 2.7 V to 30 V input range. For the TPS70933 variant, DC output accuracy is specified at -1% minimum to +1% maximum because the output voltage is 3.3 V.
The DBV version uses a 5-pin SOT-23 package with a 2.90 mm × 1.60 mm nominal body. DBV pin functions are IN on pin 1, GND on pin 2, EN on pin 3, NC on pin 4, and OUT on pin 5. A 2.2 µF or greater ceramic capacitor from OUT to ground is required to assure stability.
The regulator supports enable-controlled operation: EN high enables the device, EN low enters low-current shutdown, and EN can be left floating to enable. The device includes thermal shutdown, overcurrent protection, and reverse-current protection, with internally limited maximum output current and indefinite output short-circuit duration under the absolute maximum rating entry.

Procurement Notes
When requesting a quote for TPS70933DBVR, 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.
FAQ
What output voltage does TPS70933DBVR provide?
TPS70933DBVR is the fixed-output TPS70933 variant and provides a nominal 3.3 V regulated output. For VOUT greater than or equal to 3.3 V, the DC output accuracy is specified as -1% minimum to +1% maximum.
What input voltage range is recommended for TPS70933DBVR?
The recommended input voltage range is 2.7 V to 30 V. The electrical characteristics also list 2.7 V minimum and 30 V maximum across TA = -40°C to +85°C.
How is the enable pin used on this regulator?
The EN pin enables the device when driven high and places it into low-current shutdown when driven low. It can be left floating to enable the device, and the EN voltage must remain below 6.5 V.
What output capacitor is required for stability?
A ceramic capacitor of 2.2 µF or greater must be connected from OUT to ground to assure stability. On the DBV package, OUT is pin 5 and GND is pin 2.
