Description and Introduction

TP3052, TP3053, TP3054, TP3057, Enhanced Serial Interface CODEC/Filter COMBO Family The part **TP3057WM-X** is a **3.3V LDO Voltage Regulator** with the following specifications, descriptions, and features:  

### **Manufacturer:**  
- **Texas Instruments (TI)**  

### **Specifications:**  
- **Output Voltage:** 3.3V  
- **Output Current:** 500mA  
- **Input Voltage Range:** 4.5V to 10V  
- **Dropout Voltage:** 340mV (typical at 500mA)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 85µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SOT-223 (TO-261)  

### **Descriptions:**  
- The **TP3057WM-X** is a low-dropout (LDO) linear voltage regulator designed for stable 3.3V output.  
- It is optimized for low-power applications with high efficiency and low quiescent current.  
- Includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  

This information is sourced from Texas Instruments' official documentation. No additional guidance or suggestions are included.

Application Scenarios & Design Considerations

TP3052, TP3053, TP3054, TP3057, Enhanced Serial Interface CODEC/Filter COMBO Family

Alternative Part Number

  • MC145507DW --: Pin-compatible PCM codec/filter in the same family as the TP3057, widely available and functionally equivalent.
  • TP3054WM --: Same TP305x codec family with matching pinout and function, differing only in companding option.
  • MC145506DW --: Equivalent PCM codec/filter device with compatible interface and supply requirements, usable as a drop-in substitute.
  • MC145503P --: Pin-compatible PCM codec/filter in the same family as the TP3057, widely available and functionally equivalent for voice-band codec applications.
  • TP3054N --: Same TP305x codec family with matching pinout and function, usable as a direct functional substitute when the WM variant is unavailable.
  • MC145505P --: Alternative PCM codec-filter IC with comparable specifications and DIP package, suitable for drop-in replacement in legacy designs.
  • COMBO2-3057 --: Pin-compatible combo codec from CML Microcircuits, functionally equivalent to the TP3057 family with similar PCM interface and audio performance.
  • MC145480 --: Classic 5V PCM codec/filter with compatible serial interface and mu-law/A-law operation, widely used as a drop-in alternative in telecom designs.
  • TP3070 --: Extended temperature range combo codec from the same TP30xx family lineage but a different series number, offering similar functionality and pinout.
