TPS79628DRBR

TPS79628DRBR is a fixed-output low-dropout (LDO) regulator from TI’s TPS7962x family. It provides a stable 2.8 V rail to power microcontrollers, sensors, and other logic in portable devices. The DRBR suffix denotes a specific small-package variant with reel packaging. Key features typically include an enable pin (EN) for on/off control, low quiescent current, fast transient response, and protection features such as undervoltage, overcurrent, and thermal shutdown. It accepts an input voltage higher than 2.8 V (up to the device’s max Vin) and can deliver hundreds of milliamps, depending on the exact variant and conditions. Ideal for compact, efficient 2.8 V supplies in battery-powered designs. For precise electrical specs (Vin max, Iout max, dropout, EN threshold) and exact packaging details, consult the TI TPS79628 datasheet and product page.

TPS79628DRBR is a 2.8-V fixed low-dropout regulator (≈150 mA). There is no guaranteed one-to-one cross-reference. Equivalents are other 2.8-V fixed LDOs with similar quiescent current and dropout in the same package. Common options from other vendors include: TI TLV70028, ST LP2985-2.8, Analog Devices ADP170-2.8 (if available). For exact substitutes, use TI’s Cross-Reference tool or consult your distributor.

Note: For exact electrical specs (typical values, min/max, ESR requirements, and recommended capacitor ranges), refer to the TPS79628DRBR datasheet.

8-pin device (VSSOP-8). It is a fixed-output low-dropout regulator (LDO) with a 2.8 V output and an enable/shutdown control (EN) to turn the regulator on/off.

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures integrated circuits and components, specializing in analog, power-management, and embedded processing devices for consumer, industrial, and automotive applications.

TPS79628DRBR is a 2.8-V fixed LDO. Common application areas include:
- Portable and battery-powered devices (wearables, handhelds)
- Microcontrollers, DSPs, sensors, and ADC/DAC front ends requiring a stable 2.8-V supply
- RF/analog modules (transceivers, front-ends) needing low-noise power
- Embedded systems and IoT endpoints with local regulation from higher rails (3.3 V/5 V)
- Compact motherboard/daughterboard power rails where space and efficiency matter

TPS79628DRBR is in an 8-pin VSSOP package (VSSOP-8), typically supplied in tape-and-reel.
