General Description
The MAX889 inverting charge pump delivers a regulated
negative output voltage at loads of up to 200mA. The
device operates with inputs from 2.7V to 5.5V to produce
an adjustable, regulated output from -2.5V to -V
IN
.
The MAX889 is available with an operating frequency of
2MHz (T version), 1MHz (S version), or 0.5MHz (R ver-
sion). The higher switching frequency devices allow the
use of smaller capacitors for space-limited applica-
tions. The lower frequency devices have lower quies-
cent current.
The MAX889 also features a 0.1μA logic-controlled
shutdown mode and is available in an 8-pin SO pack-
age. An evaluation kit, MAX889SEVKIT, is available.
