General Description
The MIC5211 is a dual
μ
Cap 80mA linear voltage regulator
with very low dropout voltage (typically 20mV at light loads),
very low ground current (225
μ
A at 20mA output current), and
better than 3% initial accuracy. This dual device comes in the
miniature SOT-23-6 package, featuring independent logic
control inputs.
The
μ
Cap regulator design is optimized to work with low-
value, low-cost ceramic capacitors. The outputs typically
require only 0.1
μ
F of output capacitance for stability.
Designed especially for hand-held, battery-powered devices,
ground current is minimized using Micrel’s proprietary Super
eta PNP technology to prolong battery life. When dis-
abled, power consumption drops nearly to zero.
Key features include SOT-23-6 packaging, current limiting,
overtemperature shutdown, and protection against reversed
battery conditions.
The MIC5211 is available in dual 1.8V, 2.5V, 2.7V, 2.8V,
3.0V, 3.3V, 3.6V, and 5.0V versions. Certain mixed voltages
are also available. Contact Micrel for other voltages.
