Description and Introduction

250-mA, Ultralow IQ, Fast Transient Response, RF Low-Dropout Linear Regulator 4-DSBGA -40 to 125 The TPS72728YFFR is a low-dropout (LDO) linear regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 2.8V (fixed)  
- **Output Current:** 500mA  
- **Dropout Voltage:** 150mV (typical) at 500mA  
- **Input Voltage Range:** 2.2V to 6.5V  
- **Quiescent Current:** 17µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 70dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** DSBGA (YFF) 4-pin, 0.8mm × 0.8mm  

### **Descriptions:**  
The TPS72728YFFR is a high-performance, low-noise LDO regulator designed for power-sensitive applications. It provides a stable 2.8V output with excellent line and load transient response. Its small form factor makes it suitable for space-constrained designs.  

### **Features:**  
- **Low Dropout:** 150mV at full load (500mA)  
- **Low Noise:** Optimized for noise-sensitive applications  
- **High PSRR:** 70dB at 1kHz for improved noise rejection  
- **Low Quiescent Current:** 17µA (typical) for power efficiency  
- **Thermal Shutdown & Current Limit Protection:** Ensures safe operation  
- **Fast Transient Response:** Maintains stability under dynamic load conditions  
- **Tiny Package:** 4-pin DSBGA (0.8mm × 0.8mm) for compact PCB designs  

This information is strictly factual from the manufacturer's datasheet.

Application Scenarios & Design Considerations

250-mA, Ultralow IQ, Fast Transient Response, RF Low-Dropout Linear Regulator 4-DSBGA -40 to 125

Alternative Part Number

  • LP5907MFX-2.8/NOPB --: Low-noise 250 mA LDO in SOT-23-5 with fixed 2.8 V output, similar noise and PSRR performance, easy drop-in for many TPS72728 designs.
  • ADP151AUJZ-2.8-R7 --: Ultra-low-noise 200 mA CMOS LDO in TSOT-5 with 2.8 V fixed output, comparable dropout and PSRR, good alternative when TI supply is constrained.
  • MIC5504-2.8YM5-TR --: 300 mA low-dropout regulator in SOT-23-5 with 2.8 V fixed output, wide input range and low quiescent current, suitable functional replacement for space-constrained designs.
