Description and Introduction

200mA, Low IQ, Low Dropout Regulator for Portables 5-SC70 -40 to 125 The TLV70033DCKR 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)  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Dropout Voltage:** 150mV (typical) at 300mA load  
- **Output Current:** Up to 300mA  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** 34µA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 65dB at 1kHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**
- The TLV70033 is a low-dropout linear regulator designed for small, battery-powered applications.  
- It provides stable 3.3V output with low noise and high PSRR.  
- Features reverse current protection and thermal shutdown.  
- Stable with small ceramic capacitors (1µF or larger).  

### **Features:**
- **Low Dropout:** 150mV typical at 300mA  
- **Low Quiescent Current:** 34µA (improves battery life)  
- **High PSRR:** 65dB at 1kHz  
- **Fast Start-Up Time:** ~50µs  
- **Thermal Shutdown & Current Limit Protection**  
- **Small Package:** SC-70 (2mm × 2.1mm)  

This regulator is suitable for portable electronics, IoT devices, and power-sensitive applications.
