Description and Introduction

Vin 3V to 36V, 150mA, Ultra-Low Noise, High PSRR, Low-Dropout Linear Regulator 8-MSOP-PowerPAD -40 to 125 The TPS7A4901DGNT is a low-noise, high-PSRR (Power Supply Rejection Ratio) linear voltage regulator manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 20V  
- **Output Voltage Range:** 1.4V to 18.5V (adjustable)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at 150mA)  
- **PSRR:** 70dB (at 1kHz)  
- **Noise Performance:** 4.17µVRMS (10Hz to 100kHz)  
- **Quiescent Current:** 1mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin HVSSOP (DGNT)  

### **Descriptions:**
The TPS7A4901DGNT is a high-performance, low-dropout (LDO) linear regulator designed for applications requiring ultra-low noise and high PSRR. It is suitable for powering sensitive analog circuits, RF systems, and precision measurement devices.  

### **Features:**
- Ultra-low noise output for noise-sensitive applications.  
- High PSRR for improved power supply noise rejection.  
- Adjustable output voltage via external resistors.  
- Stable with small ceramic capacitors (≥1µF).  
- Thermal shutdown and current limit protection.  
- Wide input and output voltage range for flexibility.  
- Low dropout voltage for efficient operation.  

This regulator is ideal for applications such as medical devices, test and measurement equipment, and communication systems.
