Description and Introduction

Single and Dual Micropower High Side Switch Controllers in SOT-23 The LTC1981ES5 is a low-power, high-efficiency charge pump DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage:** Adjustable (up to ±5.5V)  
- **Output Current:** Up to 10mA  
- **Switching Frequency:** 250kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LTC1981ES5 is designed for applications requiring low-power voltage inversion or doubling. It uses a charge pump architecture, eliminating the need for inductors. The device is optimized for battery-powered systems, portable devices, and space-constrained applications.  

### **Features:**  
- No inductors required (charge pump design)  
- Low quiescent current (50µA typical)  
- Adjustable output voltage  
- Automatic shutdown when disabled  
- Compact SOT-23-5 package  
- Low output ripple  

This information is based on the manufacturer's datasheet. For detailed specifications, refer to the official documentation.

Description and Introduction

Single and Dual Micropower High Side Switch Controllers in SOT-23 The LTC1981ES5 is a high-efficiency, fixed frequency charge pump DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 5.5V  
- **Output Voltage:** -Vin (Inverting) or 2×Vin (Doubling)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 250kHz  
- **Efficiency:** Up to 96%  
- **Low Quiescent Current:** 100µA (Typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LTC1981ES5 is a versatile charge pump DC/DC converter that can generate a negative output voltage (-Vin) or double the input voltage (2×Vin). It operates with high efficiency and requires only three external capacitors, making it suitable for space-constrained applications.  

### **Features:**  
- No inductors required  
- Fixed 250kHz switching frequency  
- Low ripple and noise  
- Automatic shutdown when input is removed  
- Small footprint (SOT-23-5 package)  
- Ideal for generating bias supplies in portable and battery-powered applications  

This information is based solely on the manufacturer's datasheet.
