概要

Description

TPS78326DDCR is a fixed-output low-dropout regulator (LDO) from TI’s TPS783 family. The “26” in the name indicates the nominal output voltage, and “DDCR” denotes the package/pinout (an 8-pin device in a DDCR package). It accepts a higher input and provides a stable output with low quiescent current and good line/load regulation. Key features typically include an enable (on/off) control, current‑limit protection, thermal shutdown, short‑circuit protection, and ESD protection. It’s suitable for space‑constrained, battery‑powered designs feeding microcontrollers, sensors, and other ICs. For exact electrical specs (input voltage range, dropout at load, quiescent current, enable behavior, and pinout), consult the TI datasheet and product page.

Features

TPS78326DDCR features (highlights):
- Fixed output: 2.6 V LDO
- Low dropout regulator for efficient operation
- Enable (EN) input to shut down/regain output
- Very low quiescent current (low idle power)
- Short-circuit/overcurrent protection and thermal shutdown
- Stable with ceramic output capacitors (low ESR)
- Input voltage range suitable for common 2.5–5.5 V supplies
- Roughly up to tens-of-milliamps-to-100+ mA output capability (design depends on package/conditions)
- RoHS-compliant and packaged in the DDCR 6-pin format for small footprint and good thermal performance
- Operating temperature typically extended (e.g., −40°C to +125°C)
Note: For exact electrical specs (current limit, dropout, quiescent current, exact input range, and package details), please consult the TPS78326DDCR datasheet.

Package

SOT-23-5 (5-pin) package.

Pinout

- Pin count: 8 pins (VSSOP-8, DDCR package)
- Function: Fixed‑output low-dropout regulator (LDO) with enable; provides a regulated 2.6 V output from an input supply.

Manufacturer

Manufacturer: Texas Instruments (TI).
TI is an American multinational semiconductor company that designs and manufactures a broad range of integrated circuits, with a focus on analog and embedded processing products. It is headquartered in Dallas, Texas.

Application

TPS78326DDCR is a low-dropout fixed regulator. Typical applications: power rails for microcontrollers and digital ICs in portable/battery-powered products; IoT sensors and wearables; RF/wireless transceivers and front-end modules; audio and sensing circuits needing clean, stable supply; embedded systems in consumer electronics (cameras, set-top boxes) and medical/industrial instrumentation; small form-factor power-management sections; any application requiring a low-noise, low-quiescent-current LDO.

Equivalent

TPS78326DDCR is TI’s 2.6 V fixed LDO in an 8-pin DDCR package. For cross-references, look for other vendors’ 2.6 V fixed LDOs with similar current (~100–200 mA) and footprint. Common candidates include Microchip MIC5219-2.6/MIC5205-2.6 and Analog Devices ADP170-2.6 (verify quiescent current and package). For an exact cross, use TI’s Cross Reference tool or share your required current/footprint.
