Description

This is 1A, Positive Step-down Integrated Switching Regulator. The PT5100 modules are a series of
economical, easy-to-use 1-A positive step-down, Integrated Switching Regulators (ISRs). These ISRs are compatible with most TO-220 style linear regulators, and when employed as a linear replacement,
provide significant benefits in both efficiency and power dissipation.

Features

1. 90%+ Efficiency

2. Internal Short-Circuit Protection

3. Pin-Compatible with 3-Terminal Linear Regulators

4. Laser-Trimmed Output Voltage

5. Over-Temperature Protection

6. Small Footprint

7. Wide Input Range

Description

The AP7361 is a 1A, adjustable and fixed output voltage, ultra-low dropout linear regulator with enable. The device includes pass element, error amplifier, band-gap reference, current limit and thermal shutdown circuitry. The device is turned on when EN pin is set to logic
high level.

The characteristics of the low dropout voltage and low quiescent current make it suitable for low to medium power applications, for example, laptop computers, audio and video applications, and battery powered devices. The typical quiescent current is approximately
70µA. Built-in current-limit and thermal-shutdown functions prevent IC from damage in fault conditions.

 

Features

1. Wide input voltage range: 2.2V – 6V

2. 150mV Very Low Dropout at 300mA Load

3. 500mV Very Low Dropout at 1A Load

4. Low Quiescent Current (IQ): 70µA Typical

5. Adjustable Output Voltage Range: 1V to 5.0V

6. Fixed Output Options: 1V to 3.3V

7. Very-Fast Transient Response

8. High PSRR

9. Accurate Voltage Regulation

10. Current Limiting and Short Circuit Protection
