Description and Introduction

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 5-SC70 -40 to 125 The TPS71725DCKR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 110mV (typical) at 150mA load  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**
- The TPS71725DCKR is a low-power, high-performance LDO regulator designed for battery-powered and portable applications.  
- It provides stable voltage regulation with low noise and high PSRR.  
- Features a fast transient response and low dropout voltage, making it suitable for power-sensitive designs.  

### **Features:**
- **Low Quiescent Current:** Optimized for power efficiency.  
- **Thermal Shutdown & Current Limit Protection:** Ensures device safety.  
- **Stable with Ceramic Capacitors:** Requires only a 1µF output capacitor.  
- **Small Package:** SC-70 (DCK) for space-constrained applications.  
- **Low Noise:** Ideal for noise-sensitive analog and RF circuits.

Application Scenarios & Design Considerations

150mA, High PSRR, Low Quiescent Current, Low Noise LDO 5-SC70 -40 to 125

Alternative Part Number

  • LP5907MFX-2.5/NOPB --: Low-noise 250 mA LDO in SOT-23-5 with fixed 2.5 V output, similar dropout and noise performance, pin-compatible in function and widely available.
  • ADP151AUJZ-2.5-R7 --: Ultra-low-noise 200 mA CMOS LDO with 2.5 V fixed output in TSOT-5, comparable PSRR and dropout, suitable drop-in functional replacement.
  • MIC5219-2.5YM5-TR --: 500 mA low-dropout regulator with 2.5 V fixed output in SOT-23-5, higher current capability and similar pinout, good alternative when more headroom is needed.
