# TLV803EA30DBZR (Component) ## Description Ultra-Low-Power Voltage Supervisor (Reset IC) – Single-channel voltage supervisor designed for microcontrollers, processors, IoT devices, industrial control systems, automotive electronics, battery-powered equipment, and embedded systems requiring reliable power-on reset and brownout detection. The Texas Instruments TLV803EA30DBZR monitors a 3.0 V supply rail with a 3.08 V reset threshold, providing an active-low open-drain RESET output to ensure proper system initialization and recovery during undervoltage conditions. Features 250 nA typical quiescent current, 130 ms minimum reset timeout, supply voltage operation from 0.7 V to 6 V, and open-drain output for easy interfacing with multiple voltage domains. Includes power-on reset, brownout protection, and low-power operation, making it ideal for energy-efficient embedded applications. Operates over a −40°C to +125°C temperature range and is housed in a compact 3-pin SOT-23 (DBZ) package for surface-mount designs. #TexasInstruments #TLV803EA30DBZR #TLV803E #VoltageSupervisor #ResetIC #PowerOnReset #BrownoutDetection #LowPower #OpenDrain #PowerManagement #EmbeddedSystems #IndustrialElectronics ## Component Details - **Owner:** adrian95 - **Created:** 7/22/2026 - **Last Updated:** 8/5/2026 - **Visibility:** Public - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/26c6d6ec88e3eafb55b6479ee2983cf1708fcf4b7699b33da4317359fd0cecd6.pdf - **Part Type:** Integrated Circuits - **Symbol Style:** parametric-v1 - **Manufacturer Part Number:** TLV803EA30DBZR - **Manufacturer Name:** Texas Instruments - **Package or Case Code:** SOT-23-6 - **Used in:** 3 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
