GENERAL DESCRIPTION
The CM2836/B/C family is a positive voltage linear regulator
developed utilizing CMOS technology featured low quiescent
current (30µA typ.), low dropout voltage, and high output
voltage accuracy, making them ideal for battery applications.
EN input connected to CMOS has low bias current. The
space-saving SC70 package is attractive for “Pocket” and
“Hand Held” applications.
These rugged devices have both Thermal Shutdown, and
Current limit to prevent device failure under the “Worst” of
operating conditions.
In application requiring a low noise, regulated supply, place a
1000pF capacitor between Bypass and Ground.
The CM2836/B/C is stable with a Low ESR output
capacitance of 1.0µF or greater.

... In this state, the quiescent current is less than 2µA. This pin behaves much like an electronic switch. EXTERNAL CAPACITOR The CM2836/B/C is stable with a Low ESR output capacitor to ground of 1.0µF or greater. It can keep stable even with higher ESR capacitors. A second capacitor is recommended between the input and ground to stabilize VIN. The input capacitor should be larger than 1µ ...
