Description and Introduction

Low-Dropout, 120mA Linear Regulators The MAX8864TEUK+T is a low-dropout (LDO) linear regulator manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** Adjustable (1.25V to 5.5V) or fixed voltage options available.
- **Output Current:** Up to 150mA.
- **Dropout Voltage:** 120mV (typical) at 150mA load.
- **Input Voltage Range:** 2.5V to 6.5V.
- **Quiescent Current:** 50µA (typical).
- **Shutdown Current:** <1µA.
- **Load Regulation:** ±0.05% (typical).
- **Line Regulation:** ±0.02%/V (typical).
- **Operating Temperature Range:** -40°C to +85°C.
- **Package:** SOT23-5.

### **Descriptions:**
- The MAX8864TEUK+T is a low-noise, low-dropout linear regulator designed for battery-powered applications.
- It provides stable output voltage with low quiescent current, making it suitable for portable devices.
- Features include reverse-battery protection, thermal shutdown, and current limiting.

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.
- **Low Noise:** Optimized for noise-sensitive applications.
- **Low Quiescent Current:** Extends battery life in portable devices.
- **Thermal Shutdown & Current Limit:** Protects the device from overheating and overcurrent conditions.
- **Reverse-Battery Protection:** Safeguards against incorrect battery connections.
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors as small as 1µF.

This information is based solely on the manufacturer's datasheet for the MAX8864TEUK+T.
