General Description
The MAX8869 low-dropout linear regulator operates
from a +2.7V to +5.5V input and delivers a guaranteed
1A load current with a low 200mV dropout. The high-
accuracy (±1%) output voltage is preset at +5V, +3.3V,
+2.5V, +1.8V, or +1.0V or is adjustable from +0.8V to
+5V with an external resistor-divider.
The MAX8869 uses MicroCap technology and
requires only a small 1μF output capacitor for guaran-
teed stability. An internal PMOS pass transistor allows
low 500μA supply current, making this regulator useful
for networking and telecom hardware as well as bat-
tery-operated equipment. Other features include soft-
start, low-power shutdown, short-circuit protection, and
thermal shutdown protection.
The MAX8869 is available in a 1.5W, 16-pin TSSOP
package, which is 30% smaller than a SOT223 and only
1.1mm high.
