Description

TPS79628DRBR is a Texas Instruments fixed-output low-dropout (LDO) regulator from the TPS796 family. It provides a stable 2.8 V output from a higher input voltage, intended to power logic and memory rails in portable/embedded systems. Key points:
- Fixed 2.8 V output
- Low dropout, low quiescent current
- Line and load regulation with protection features (current limit/thermal shutdown)
- Enable (EN) control to turn the regulator on/off
- DRBR suffix indicates the D-pack/SMD package and reel packaging
Typical uses include microcontrollers, memories, and sensors in battery-powered devices. For exact specs (input range, dropout voltage, max current, EN behavior) refer to the TI TPS79628DRBR datasheet.

Features

Key features of TPS79628DRBR (TI LDO):
- Fixed output: 2.8 V
- Ultra-low quiescent current for battery-powered apps
- Low dropout voltage for efficient operation
- Overcurrent/short-circuit protection and thermal shutdown
- Enable/disable control to minimize leakage when off
- Stable with a wide range of output capacitors and ESR values
- Good line and load regulation and transient response
- Small DRBR package (8-pin, lead-free) suitable for compact designs
Note: For exact electrical specs (current capability, input range, dropout, PSRR, capacitor recommendations), refer to the TI TPS79628DRBR datasheet.

Package

TPS79628DRBR is in an 8-pin VSSOP (Very Small Outline Package) package.

Pinout

- Pin count: 8 pins (in the DRBR package).
- Function: Fixed‑output low‑dropout regulator (TPS79628) with a 2.8 V output. Includes VIN, VOUT, GND, and EN (enable) pins; EN can enable/disable the regulator.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- Company type: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits for global use.

Application

TPS79628DRBR is a fixed 2.8 V LDO regulator. Typical application areas:
- Battery-powered/portable devices needing a stable 2.8 V rail
- Microcontrollers, DSPs, memory and other IC supplies
- Sensors and analog front-end circuits
- Wireless/RF modules and IoT nodes (BLE, Zigbee, etc.)
- Wearables and handheld instruments
- Embedded systems requiring a low-noise, reliable regulator
