Description and Introduction

Cap-Free, NMOS, 250mA Low Dropout Regulator with Reverse Current Protection The TPS73233DBVR is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 250mA  
- **Dropout Voltage:** 34mV (typical) at 100mA load  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Accuracy:** ±1% (over line, load, and temperature)  
- **Quiescent Current:** 20µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 75dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS73233DBVR is a low-noise, low-dropout linear regulator designed for applications requiring high performance and small footprint. It provides stable 3.3V output with excellent line and load transient response. The device includes features like reverse current protection, thermal shutdown, and short-circuit protection.  

### **Features:**  
- **Low Dropout Voltage:** Enables operation with very small headroom.  
- **High PSRR:** Reduces noise from input supply variations.  
- **Low Quiescent Current:** Improves efficiency in battery-powered applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors (≥1µF).  
- **Protection Features:**  
  - Thermal shutdown  
  - Short-circuit protection  
  - Reverse current protection  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Cap-Free, NMOS, 250mA Low Dropout Regulator with Reverse Current Protection

Alternative Part Number

  • LP2985AIM5-3.3 --: Low-dropout 3.3V linear regulator in SOT-23-5 with similar current capability and pin-compatible footprint, widely used as a direct substitute.
  • MIC5205-3.3YM5 --: 3.3V LDO regulator in SOT-23-5 with comparable dropout and output current, offering a different vendor option for the same application.
  • AP2112K-3.3TRG1 --: 3.3V fixed LDO in SOT-23-5 with low quiescent current and similar electrical characteristics, suitable as a cost-effective alternative.
  • MIC5219-3.3YM5 --: 3.3V LDO regulator in SOT-23-5 with low dropout and good noise performance, suitable drop-in replacement for many TPS73233 applications.
