Description
The UPC2905B is a three-terminal low dropout voltage regulator in the IC Chips product category. It is constructed with a PNP output transistor and is part of the µPC2900 series. This series features the ability to source 1A of output current with a low dropout voltage of typically 0.7V. The power dissipation of the µPC2900 series is significantly lower compared to conventional three-terminal positive voltage regulators with NPN output transistors. Additionally, the UPC2905B is compatible with low voltage outputs (3V, 3.3V), which is not common in conventional low dropout regulators such as the µPC2400A series.
Specifications and features
- Output current in excess of 1.0A
- Low dropout voltage VDIF= 0.7V TYP. (at IO= 1A)
- On-chip overcurrent and thermal protection circuit
- On-chip output transistor safe area protection circuitApplication Scenarios
The UPC2905B can be used in various electronic applications that require a low dropout voltage regulator. It is commonly utilized in devices that require stable and regulated voltage supply, such as power management circuits, battery-powered systems, and portable electronic devices.
