Description
TPS79915DDCR is TI’s fixed-output low-dropout regulator (LDO) in the TPS799 family. It delivers a stable 1.5-V rail from a higher input supply for digital ICs, MCUs, and sensors in battery-powered designs.
Key features
- Fixed 1.5 V output
- Low quiescent current for long battery life
- Enable (EN) control to turn the regulator on/off
- Protection: short-circuit/overcurrent and thermal shutdown
- Stable with ceramic output capacitors
- Available in the compact DDCR package
Packaging: DDCR (small, surface-mount).
Typical applications: portable electronics, wearables, MCU power rails, and sensor nodes.
Note: For exact input-range, maximum load/current, dropout, capacitor ESR requirements, and pinout, consult the official TI datasheet and product page.

Equivalent
TPS79915DDCR is a fixed 1.5 V LDO regulator (~150 mA). Common cross-references (drop-in style equivalents) include: LM1117-1.5, AMS1117-1.5, MIC5205-1.5, MCP1700-1.5, MCP1703-1.5. Note that package, enable, and quiescent current differ; verify pinout and footprint before substituting.
Features
Here are the main features of the TI TPS79915DDCR (fixed 1.5 V LDO):
- Fixed output: 1.5 V
- Output current: up to 150 mA
- Input voltage range: ~1.8 V to 5.5 V
- Low dropout voltage (typical in the few hundred mV at 150 mA)
- Enable (EN) pin for enable/disable control
- Very low quiescent current; low power consumption in operation and shutdown
- Protection: current limit and thermal shutdown
- Stability: requires an output capacitor for stability (typical 1 µF to 10 µF; ceramic caps acceptable with proper ESR)
- Suitable for compact layouts due to small package (DDCR variant)
Note: Exact package details and minimum ESR requirements are specified in the datasheet for the TPS79915DDCR.
