- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The TPS7101QPWR is a low-power, low-dropout linear regulator designed for battery-powered applications.  
- It provides a stable output voltage with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes thermal shutdown and current limit protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for power-sensitive applications.  
- **Thermal Shutdown and Current Limit Protection:** Enhances device reliability.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors.  
- **Enable Pin (EN):** Allows for power-saving shutdown mode.

Application Scenarios & Design Considerations

Lowest Dropout (LDO) PMOS Adjustable Voltage Regulator

Alternative Part Number

  • LP2951ACM-3.3/NOPB --: Low-dropout linear regulator in the same family of adjustable/fixed LDOs, widely used as a drop-in substitute for TPS7101 series with similar current and voltage ratings.
  • MIC5205-3.3YM5-TR --: Pin-compatible low-dropout regulator from a different vendor and series, offering comparable dropout and load capability for TPS7101 applications.
  • LM317LZ/NOPB --: Classic adjustable linear regulator with a different naming series, suitable as a functional replacement where adjustable output and moderate current are required.
