Descripción general

Description

TPS78319DDCR is a fixed-output low-dropout regulator from Texas Instruments in the DDCR package. It provides a precise 1.9 V output rail with low quiescent current, making it suitable for battery-powered and space-constrained electronics.
Key points:
- Fixed 1.9 V output
- Enable/shutdown control and protection features (short-circuit/thermal protection)
- Low quiescent current and good line/load regulation
- Requires a stable, low-ESR output capacitor
- Input voltage range and maximum current per the datasheet (design to your application)
Typical uses include powering MCU cores, sensors, and other logic in portable or compact devices. For exact electrical specs, capacitor requirements, and pinout, consult the TPS78319DDCR datasheet. If you want, I can summarize the full datasheet or point to the specific sections.

Features

TPS78319DDCR features (highlights):
- Fixed 1.9 V output LDO (TPS78319 family)
- Input voltage range up to 5.5 V
- Ultra-low quiescent current for efficiency
- Low dropout suitable for battery-powered apps
- Enable pin for controlled turn-on/off
- Protection: overcurrent/short-circuit and thermal shutdown
- Stable with ceramic output capacitors (low ESR)
- 8-pin DDCR (VSSOP-8) package
- Suitable for compact, portable electronics and microcontroller supplies
- RoHS-compliant, Pb-free package options

Package

I can’t fetch the datasheet directly here. For TPS78319DDCR, check Texas Instruments’ datasheet/ordering information: "DDC" is the package code and "R" denotes tape-and-reel. The datasheet’s ordering table and mechanical data give the exact package name and dimensions.

Pinout

TPS78319DDCR is supplied in a 5‑pin SOT‑23 (DDC) package. It is a low‑dropout (LDO) linear regulator (fixed output) whose pins provide: VIN (input), VOUT (regulated output), GND (ground), EN (enable/shutdown), and BYP/ADJ (bypass/setting capacitor or trim function). For exact pin numbering, electrical characteristics and recommended external components, see the Texas Instruments TPS783 datasheet.

Manufacturer

Manufacturer: Texas Instruments (TI).
TI is an American multinational semiconductor company that designs and manufactures analog and embedded processing chips, power‑management ICs (like the TPS7/TPS78x series), microcontrollers and related semiconductor products. It’s one of the world’s largest analog semiconductor vendors and a major supplier to industrial, automotive, consumer and communications markets.

Application

TPS78319DDCR is TI’s 1.9-V low-dropout regulator (DDCR). Ideal for:
- Battery-powered/portable devices (wearables, handhelds)
- Microcontroller/SoC core and peripheral rails
- RF/wireless and sensor modules
- Analog/digital biasing supplies
- Automotive electronics needing compact LDOs
Notes: low quiescent current and low dropout suit space- and power-constrained designs.
