Description

TPS79625DCQ is a fixed-output, low-dropout (LDO) linear regulator from Texas Instruments. It provides a stable 2.5 V rail from a higher input supply, suitable for portable and battery-powered electronics.
Key features
- Fixed 2.5 V output
- Enable/shutdown control
- Overcurrent and thermal protection
- Low dropout for modest headroom between VIN and VOUT
- Ultra-low quiescent current (typical)
Package
- DCQ: a compact TI QFN-style package
Typical applications
- MCU, sensors, memory, and other low-power rails in wearables and handheld devices
How to use (high level)
- Connect VIN to the supply and VOUT to the load
- Add recommended input/output capacitors (low-ESR) per the datasheet
- Tie EN high to enable (low to disable)
- Ensure adequate thermal management
For exact electrical specs, package details, and layout guidance, consult the TI TPS79625DCQ datasheet and product page.

Features

TPS79625DCQ is a fixed-output low-dropout regulator from TI. Key features:
- Fixed output: 2.5 V
- Max load current: up to several hundred mA (typical around 250 mA)
- Low dropout voltage for efficient operation
- Very low quiescent current
- Enable (EN) input for shutdown control
- Protective features: thermal shutdown and current-limit protection
- Strong line/load regulation and PSRR
- Suitable for small, low-profile packages (DCQ variant)
Note: exact current rating, dropout, and input range can vary by device revision; consult the datasheet for precise numbers.

Package

TPS79625DCQ is in an 8-pin VSSOP package (VSSOP-8).

Pinout

8 pins. It is a fixed 2.5 V low-dropout regulator (LDO) with an enable pin; takes input up to about 5.5 V and provides a regulated 2.5 V output when enabled.

Manufacturer

Manufacturer: Texas Instruments (TI).
Kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits and embedded processing solutions used in a wide range of electronic devices.

Application

TPS79625DCQ is a fixed 2.5-V LDO in a compact package. Typical applications:
- Generate a clean 2.5-V rail in embedded systems (MCUs, memories, logic cores, PMIC rails)
- Power noise-sensitive analog/digital front-ends (op-amps, ADC/DAC, sensors, RF transceivers)
- Battery-powered/mobile devices requiring low quiescent current and small footprint
- Post-regulation stage after switching regulators
- Small handheld devices and wearables with space constraints

Equivalent

TPS79625DCQ is TI’s fixed 2.5 V low-dropout regulator (about 150 mA). There isn’t a single universal cross‑reference. For exact substitutes, use TI’s Cross Reference tool. In general, other vendors’ 2.5 V fixed LDOs with similar current include Microchip MCP1700-2.5 and AMS1117-2.5; however, verify dropout, quiescent current, and package/pinout to ensure compatibility.
