Description
The UPC2908T-E1 is a three-terminal low dropout voltage regulator in the µPC2900 series. It is a positive voltage regulator constructed with a PNP output transistor. This series features the ability to source 1 A of output current with a low dropout voltage of typically 0.7 V. Compared to conventional voltage regulators with NPN output transistors, the power dissipation of the µPC2900 series can be drastically reduced. The UPC2908T-E1 also supports low voltage outputs (3 V, 3.3 V), which are not available in the conventional low dropout regulators (µPC2400A series).
Specifications and features
The UPC2908T-E1 has the following specifications and features:
- Output current in excess of 1.0 A
- Low dropout voltage VDIF=0.7 V TYP. (at IO= 1 A)
- On-chip overcurrent and thermal protection circuit
- On-chip output transistor safe area protection circuit
Application Scenarios
The UPC2908T-E1 is ideal for applications that require a low dropout voltage and can benefit from the low power dissipation provided by the PNP output transistor. Some possible application scenarios include:
- Power supply circuits for portable devices
- Battery-powered systems
- Power management in automotive electronics
Comparison
The UPC2908T-E1 offers several advantages and disadvantages compared to other voltage regulators.
Advantages- High output current capability
- Low dropout voltage
- On-chip overcurrent and thermal protection circuit
- On-chip output transistor safe area protection circuit
Disadvantages- Not compatible with conventional low dropout regulators (µPC2400A series) for low voltage output
