com LX1882 I N T E G R A T E D P R O D U C T S Charge Pump Doubler with Linear Regulator P RODUCTION D ATA S HEET DESCRIPTION The LX1882 is a two-stage boost regulator featuring a charge pump doubler with an integrated low dropout linear regulator.
This configuration allows for a low noise boosted output for powering noise sensitive applications.
The first stage features an internal doubler charge pump converting an input supply of 1.
8V to 4.
4V, while the second stage is an LDO regulating the boosted voltage converting it to a low noise output.
The LX1882 is capable of supplying up to 50mA of output current with an operating current of less than 150µA.
Quiescent current is reduced to < 5µA in shutdown mode.
The LX1882’s internal regulator is stable with either Tantalum or Ceramic low-value capacitors, typically 2.
2µF on the output, allowing designers flexibility in external component selection.
Reliability and safety features include Thermal Shutdown Protection and I...
