LX1882
Charge Pump Doubler with Linear Regulator
PRODUCTION DATA SHEET
I N T E GR A T ED
PRO DUC T S
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 150
A.
Quiescent current is reduced to < 5
A in
shutdown mode.
The LX1882’s internal regulator is stable
with either Tantalum or Ceramic low-value
capacitors, typically 2.2
F on the output,
allowing designers flexibility in external
component selection.
Reliability and safety features include
Thermal
Shutdown
Protection
and
Integrated Short-Circuit Protection.
