TPS70938DBVR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS70938DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Unregulated input supply, 2.7 V to 30 V (abs-max 32 V). Bypass to GND with a 2.2 µF or larger ceramic capacitor close to the pin.
2 GND power_in Device ground reference. All voltages in the datasheet are specified with respect to this pin.
3 EN input Active-high enable input. Drive high (VIH ≥ 0.9 V) to enable the regulator; drive low (VIL ≤ 0.4 V) to enter low-current shutdown (150 nA typ). Can be left floating to enable the device. Maximum voltage 6.5 V.
4 NC unconnected No internal connection. Leave floating or tie to GND per board convention.
5 OUT power_out Regulated 3.8 V output (TPS70938), 150 mA continuous with 200 mA peak, ±2 % accuracy over temperature. Requires a 2.2 µF or larger ceramic capacitor to GND for stability.

CAD (KiCad official)

  • Symbol: TPS70938DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tps70938dbvr-etched.step / tps70938dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps70938dbvr.step / tps70938dbvr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (None pp, sha256 c2e78bfb71f627cf, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
