5x Regulated Step Down Charge Pump VPA1000 Description The VPA1000 is a low voltage 0.
5x regulated step-down charge pump.
It is designed as a low cost replacement for inductor-based step-down switching regulators (buck), or a high efficiency replacement for linear regulators (LDO).
At full load, it can save nearly 500mW of power compared to a standard LDO, making it ideal for low cost battery powered applications.
The VPA1000 can also be put in a micro-power shutdown mode with 1µA nominal input current to extend battery life when not in use.
The VPA1000 is available in a TSOT-6 package and characterized over the industrial temperature range of -40°C to +85°C.
