Specifications

  • Input voltage range: 2.7V to 5.5V
  • Output voltage range: 0V to VCC
  • Maximum continuous current: 500mA
  • Operating temperature range: -40°C to 85°C

Detailed Pin Configuration

  1. EN (Enable)
  2. IN (Input Voltage)
  3. GND (Ground)
  4. OUT (Output Voltage)
  5. FLT (Fault Indicator)
  6. NC (No Connection)
  7. NC (No Connection)
  8. VCC (Supply Voltage)

Functional Features

  • Overcurrent protection: The TPS2042DR automatically shuts off the output when the current exceeds the specified limit.
  • Thermal shutdown protection: It safeguards against excessive heat by shutting down the device temporarily.
  • Fault indicator: The FLT pin provides a visual indication when a fault condition occurs.

Advantages and Disadvantages

Advantages

  • Efficient power distribution control
  • Reliable overcurrent and thermal protection
  • Compact size and easy integration
  • Visual fault indication for quick troubleshooting

Disadvantages
