Description and Introduction

1.5-A Low Dropout Voltage Regulators with Power Good 20-HTSSOP -40 to 125 The TPS75101QPWPG4 is a voltage regulator manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.2V to 5.5V  
- **Output Current:** Up to 1A  
- **Dropout Voltage:** 300mV (typical at 1A)  
- **Quiescent Current:** 85µA (typical)  
- **Switching Frequency:** 1.5MHz (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
- The TPS75101QPWPG4 is a low-dropout (LDO) linear regulator with an integrated power MOSFET.  
- It is designed for high-performance, low-noise applications requiring precise voltage regulation.  
- The device includes features like thermal shutdown, current limit, and power-good monitoring.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Power-Good (PG) Indicator:** Monitors output voltage status.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load currents.  
- **Stable with Low-ESR Ceramic Capacitors:** Reduces external component count.

Application Scenarios & Design Considerations

1.5-A Low Dropout Voltage Regulators with Power Good 20-HTSSOP -40 to 125

Alternative Part Number

  • TPS75101QPWP --: Same TPS75101 series LDO regulator in the same HTSSOP-20 PowerPAD package, identical electrical specifications; the G4 suffix only denotes lead-free/RoHS green packaging, so this is a direct drop-in replacement.
  • TPS7A4700RGWR --: Low-noise adjustable LDO from a different TI series with comparable input voltage range and current capability; a good functional alternative when the exact TPS75101 series is unavailable, though pinout and package differ so layout changes are required.
  • LT1963AEQ --: Widely available adjustable low-dropout regulator with similar voltage and current ratings from a different manufacturer and series, suitable as a cross-vendor second source with minor circuit and footprint adjustments.
