Descripción general

Description

TLV809EA29DBZR is a Texas Instruments device in the TLV809 family, a fixed-output voltage reference (2.9 V). It’s designed to provide a precise, low-noise reference for analog circuits, ADCs/DACs, and precision instrumentation, with low quiescent current and good line/load regulation in a compact SMD package (DBZR suffix denotes the specific package/reel options).
Key points:
- Fixed output: about 2.9 V (A29)
- Purpose: stable reference for analog front-ends
- Characteristics to check in the datasheet: initial accuracy, temperature coefficient, noise, line/load regulation, and package/pinout
- Package suffix DBZR indicates form factor and packaging
For exact electrical specs, packaging details, and pin configuration, refer to the TI TLV809EA29DBZR datasheet. If you’d like, I can fetch or summarize the specific topology and electrical parameters.

Features

TLV809EA29DBZR is a fixed-threshold voltage detector/reset supervisor. Key features:
- Fixed threshold: 2.9 V (EA29)
- Ultra-low quiescent current: typical around 1 µA (very low bias in operation)
- Wide operating supply range: roughly 1.8–5.5 V
- Power-on reset: ensures a valid reset until Vcc is stable above threshold
- Reset output: active-low and logic-compatible
- Temperature range: typically -40 °C to +125 °C
- Packaging: compact, RoHS Pb-free (DBZR) style (tape-and-reel option)
- Suitable for battery-powered/microcontroller supervision
Note: exact output drive (push-pull/open-drain) and timing specs are defined in the datasheet for this variant.

Package

SOT-23-3 (SC-70-3) package. The trailing "R" indicates tape-and-reel packaging.

Pinout

- Pin count: 3 pins (SOT-23-3/DBV package).
- Function: Fixed-threshold voltage supervisor (reset IC). Monitors Vcc and outputs an active-low reset when the supply falls below ~2.9 V (also during power-up/power-down).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A global American semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

TLV809EA29DBZR is a 2.9 V threshold voltage supervisor (reset IC) used to monitor VDD and generate reset for MCUs and digital ICs. Applications: microcontroller brown-out/power-on reset; battery-powered/portable devices (IoT, wearables, sensors); supply-glitch protection; automotive/industrial electronics needing reliable reset on supply droop.
