TPS78319DDCR

TPS78319DDCR is TI’s fixed-output low-dropout regulator (LDO) in the TPS783 family. It delivers a stable 1.9 V rail from a higher input supply, with features suited for battery-powered or space-constrained designs.
Key points:
- Fixed output: 1.9 V
- Low dropout and low quiescent current for efficiency in portable apps
- Enable (or power-down) control pin
- Protection: current limit and thermal shutdown
- Packaging code DDCR indicates a specific TI package option (pinout/mechanical details in the datasheet)
Applications: powering microcontrollers, sensors, analog/RF blocks, and other small embedded circuits requiring a clean 1.9 V supply.
For exact electrical specs (input range, dropout at load, tolerance, current limit) and the precise package/pinout, consult the TPS78319DDCR datasheet and TI product page.

TPS78319DDCR is TI’s fixed 1.9 V, 150 mA LDO (TPS7831x family). Direct replacements include other TI TPS7831x parts with the same 1.9 V option in different packages. Cross-references from other vendors depend on package and tolerance; common 1.9 V, ~150 mA LDOs include Microchip MIC5319, On Semiconductor NCP468x, Analog Devices ADP170.
