Description and Introduction

Cap-Free, NMOS, 400mA Low Dropout Regulator with Reverse Current Protection The TPS73633DBVT is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 400mA  
- **Dropout Voltage:** 110mV (typical) at 400mA  
- **Input Voltage Range:** 2.2V to 5.5V  
- **Accuracy:** ±1.5% (over line, load, and temperature)  
- **Quiescent Current:** 400µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Junction Temperature:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS73633DBVT is a low-noise, high-PSRR (Power Supply Rejection Ratio) LDO regulator designed for precision voltage regulation in portable and battery-powered applications. It features fast transient response and stable operation with low-ESR ceramic capacitors.  

### **Features:**  
- **Low Dropout:** 110mV at 400mA  
- **High PSRR:** 70dB at 1kHz  
- **Low Noise:** 30µVRMS (10Hz to 100kHz)  
- **Thermal and Overcurrent Protection**  
- **Stable with Ceramic Capacitors (≥1µF)**  
- **Fast Start-Up Time**  
- **Enable Pin for Power Management**  

This regulator is commonly used in applications such as portable electronics, medical devices, and industrial systems requiring stable and efficient power management.

Application Scenarios & Design Considerations

Cap-Free, NMOS, 400mA Low Dropout Regulator with Reverse Current Protection

Alternative Part Number

  • LP38693SD-3.3/NOPB --: Low-dropout 3.3V linear regulator in SOT-23-5 with similar current capability and pin-compatible footprint, offering a different series naming for easy distinction.
  • MIC5219-3.3YM5-TR --: 3.3V LDO regulator in SOT-23-5 with comparable dropout and load current, from a different manufacturer and series, suitable as a drop-in alternative.
  • AP2112K-3.3TRG1 --: 3.3V fixed LDO in SOT-23-5 with low quiescent current and stable output, providing a cost-effective alternative from a distinct series.
