Description and Introduction

Dual-Output LDO Voltage Regulators The TPS70151PWPR is a dual-output power management IC (PMIC) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI) / Burr-Brown (BB)  
- **Part Number:** TPS70151PWPR  
- **Package:** HTSSOP (PW) - 20-pin PowerPAD™  
- **Output Voltage 1 (VOUT1):** 1.5V (fixed)  
- **Output Voltage 2 (VOUT2):** Adjustable (1.2V to 5.5V)  
- **Input Voltage Range (VIN):** 2.7V to 5.5V  
- **Output Current (IOUT1/IOUT2):** Up to 1A (shared between outputs)  
- **Switching Frequency:** 550kHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The TPS70151PWPR is a dual-output, low-dropout (LDO) voltage regulator with integrated power sequencing. It is designed for applications requiring precise power management, such as DSPs, FPGAs, and microcontrollers. The device features a fixed 1.5V output and an adjustable output (1.2V to 5.5V), providing flexibility for various system requirements.  

### **Features:**  
- **Dual-Output Regulator:** Combines a fixed 1.5V LDO and an adjustable LDO in a single package.  
- **Power Sequencing:** Built-in sequencing control for proper power-up/down of sensitive loads.  
- **Low Dropout Voltage:** Optimized for battery-powered applications.  
- **Thermal & Overcurrent Protection:** Ensures safe operation under fault conditions.  
- **PowerPAD™ Package:** Enhances thermal performance for high-power applications.  
- **Low Quiescent Current:** Improves efficiency in standby modes.  

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

Application Scenarios & Design Considerations

Dual-Output LDO Voltage Regulators

Alternative Part Number

  • LP38693SD-3.3/NOPB --: Low-dropout linear regulator in a similar power-management role with a different series prefix, offering comparable regulation performance for designs needing a simple LDO replacement.
  • MIC5219-3.3YM5-TR --: Alternative LDO regulator from a different manufacturer and naming series, suitable when the dual-output TPS70151 function can be replaced by a single-rail regulator with similar current capability.
  • AP2112K-3.3TRG1 --: Widely available LDO regulator with a distinct part-number series, providing a cost-effective substitute for low-power supply rails in similar applications.
  • LP3965EMP-1.5 --: Dual/dual-output LDO family with 1.5V fixed output and similar current capability; different series name makes it easy to distinguish from the source.
  • MIC5219-1.5YM5 --: Low-dropout linear regulator with 1.5V fixed output and comparable package/current rating; different manufacturer and series provide a clear alternative.
  • AP2112K-1.5TRG1 --: 1.5V fixed LDO regulator in a small SOT-23-5 package with similar electrical characteristics; different naming and vendor make it a distinguishable substitute.
