MAX8882 Datasheet, PDF (1/8 Pages) Maxim Integrated Products – Dual, Low-Noise, Low-Dropout, 160mA Linear Regulators in SOT23

19-1818; Rev 1; 10/01
Dual, Low-Noise, Low-Dropout, 160mA Linear
Regulators in SOT23
General Description
The MAX8882/MAX8883 dual, low-noise, low-dropout
linear regulators operate from a +2.5V to +6.5V input
and deliver up to 160mA each of continuous current.
Both versions offer low output noise and low dropout of
only 72mV at 80mA. Designed with an internal P-
channel MOSFET pass transistor, the MAX8882/
MAX8883 maintain a low 165µA supply current (both
LDOs on), independent of the load current and dropout
voltage. Other features include short-circuit protection
and thermal-shutdown protection. The MAX8882 has a
single shutdown input and provides an external refer-
ence bypass pin to improve noise performance. The
MAX8883 includes two independent logic-controlled
shutdown inputs. The MAX8882/MAX8883 are both
available in a miniature 6-pin SOT23 package.
