Description and Introduction

High-Frequency, Regulated, 200mA, Inverting Charge Pump The MAX889RESA-T is a voltage regulator IC manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX889RESA-T  
- **Package:** 8-Pin SOIC  
- **Output Voltage:** Adjustable or Fixed (specific value depends on variant)  
- **Input Voltage Range:** Up to 5.5V (exact range may vary)  
- **Output Current:** Typically up to 150mA (check datasheet for exact rating)  
- **Dropout Voltage:** Low dropout (specific value depends on conditions)  
- **Quiescent Current:** Low (exact value varies with model)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX889RESA-T is a low-dropout (LDO) linear voltage regulator designed for low-power applications.  
- It provides stable output voltage with minimal noise, making it suitable for portable and battery-powered devices.  
- Available in a small SOIC package for space-constrained designs.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal and Short-Circuit Protection:** Enhances reliability under fault conditions.  
- **Stable with Low-ESR Capacitors:** Works with ceramic capacitors for cost-effective designs.  
- **Adjustable or Fixed Output Options:** Depending on variant.

Application Scenarios & Design Considerations

High-Frequency, Regulated, 200mA, Inverting Charge Pump

Alternative Part Number

  • LT1054CS8#PBF --: Pin-compatible switched-capacitor voltage inverter in SO-8 with similar current capability; widely available and a common drop-in for MAX889 designs.
  • ICL7660ACBAZA --: Classic charge-pump voltage inverter in SO-8, functionally similar for negative supply generation; lower cost and broad availability.
  • TC7660EOA --: SO-8 charge-pump inverter with comparable topology and voltage range; suitable when exact MAX889 features are not critical.
